EDITOR'SDESK Mistaken Communication While some people took offense at a comment I wrote earlier, I think it was really just a misunderstanding.
A
pparently, some people took exception to my comments and opinions in the March issue. Specifically, there was opposition to my mention that renewable energy from a business standpoint was not worth the investment. Opponents thought I was taking the side of business and saying that the environment did not matter when compared to profits. I think there was a misunderstanding. I suppose that has to be my responsibility since communication is my business. Everyone makes business decisions each day. Where will I buy gasoline? Which lamp should we buy? Where should we get our new refrigerator? In my family, I have to weigh what I would like to buy against the money in my pocket and that usually means I cannot do everything that I want to. I have to make a business decision. I have watched the development of solar panels, LED lighting, wind power, etc. for many years. I would like to put these technologies and perhaps others to work for me. However the investment takes 10 to 15 years to save in energy costs to make up the price I would have to pay. I don’t have the capital today to invest in tomorrow’s return. That is my business decision and I suspect that is why others are not rushing to their local green shop to buy these products either. That will change in my opinion. Eventually there will be a breakthrough that will make it more affordable as well as more accessible to the average person. But it may take some time to get there; how many decades did we talk about “the longer lasting light
bulb” as some sort of future-tech MacGuffin before we all started buying the twisty halogens? I saw a news item about a town in New Jersey. The local utility decided to place solar panels on many of the utility poles throughout the town. The labor to erect these panels is pretty high and the utility will need to raise rates to keep the project going. The populace is not pleased. Solar usage is expected to decline in Europe as governments are starting to cut back on tariff support. To the positive side, Professor Daniel Nocera from the Massachusetts Institute of Technology recently launched a new company named Sun Catalytix to manufacture a device that mimics nature’s photosynthetic process. The process needs only water to generate power. The power is storable and can feed a fuel cell during the night or very low sun times. See my blog titled Turning Over a New Leaf for more information. So while I stand by my original opinion, I also think that as science continues to advance and prices come down, the world will easily adopt a new energy plan. It will be as natural as the adoption of putting gasoline into the horseless carriage over 100 years ago. PE

The EPA has issued a final rule that extends the deadline for reporting 2010 data under the Greenhouse Gas (GHG) Reporting Program to Sept. 30, 2011. The original deadline was March 31, 2011. The agency had previously announced its intention to extend the deadline on March 1, 2011. Under the GHG Reporting Program, entities required to submit data must register with the electronic GHG reporting tool (e-GGRT) no later than 60 days before the reporting deadline. With this reporting deadline extension, the new deadline for registering with e-GGRT is Aug. 1, 2011. The extension will allow the agency to further test the system by giving the industry the opportunity to use it and provide feedback. The EPA’s GHG Reporting Program, launched in October 2009, requires reporting GHG data from large emission sources across a range of industry sectors, as well as suppliers of products that would emit GHGs if released or combusted. The data will help guide policy decisions and the development of future programs, which the Agency might implement to reduce such emissions. It will also help industries and businesses find ways to be more efficient and save money. More information on these actions is available at www.epa.gov/climatechange/emissions/extension.html.

EU Emissions Increase According to data released by the European Commission on Climate Action, industrial and utility emissions increased in 2010 by about 3 percent. Analysts said this represented the first increase in three years. They said the major reason for the increase was the exceptionally cold winter that boosted energy consumption for heating. Economists said that while carbon allowances had decreased, there was still an oversupply. In 2009 there were allowances of 4.8 percent and the figure decreased to 1.9 percent in 2010.

LEGALLOOKOUT By Lynn L. Bergeson
A Dangerous List California has proposed Prop 65 Listings under the Labor Code mechanism, but using such listing methods could set a dangerous precedent. n March 4, 2011, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed to list four chemicals as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act (Prop 65) based on the Labor Code mechanism contained in Health and Safety Code Section 25249.8(a). The four substances are: cyclopenta[cd]pyrene, ethanol in alcoholic beverages, leather dust and salted fish, Chinese-style.
O
Background Prop 65 was enacted in 1986 to protect citizens and the state’s drinking water sources from chemicals known to cause cancer, birth defects or other reproductive harm, and to inform citizens about exposures to such chemicals. Prop 65 requires the governor to publish, at least annually, a list of such chemicals. Chemical product manufacturers, distributors and formulators have been challenged to label their products accordingly and make appropriate notifications, or determine the requirements do not apply because of safe harbor provisions. Historically, OEHHA has relied upon the authoritative body, qualified experts or formally required mechanisms to list chemicals. In 2008, OEHHA requested comment on the utility of another listing mechanism, namely listing any substance identified by Labor Code sections 6382(b) (1) and 6382(d). That code references chemicals identified as carcinogens by the International Agency for Research on Cancer (IARC), while Labor Code section 6382(d) references chemicals listed pursuant to the federal Hazard Communications Standard (HCS), under regulations found at 29 C.F.R. section 1910.1200, which includes known and probable carcinogens identified by IARC, substances identified as known or probable carcinogens by the National Toxicology Program (NTP), and several other substances identified as carcinogens by the federal Occupational Safety and Health Act. Industry strongly objected to using the Labor Code mechanism. They said the proposal would allow chemicals with no public input or OEHHA opportunity to comment on the underlying science of the listing, which is very different from the other listing mechanisms. In 2009, the Alameda County Superior Court with OEHHA finding that Prop 65 imposed a “clear ministerial duty” to list substances known to cause cancer or reproductive toxicity as identified by reference to the
Labor Code. Appeals are ongoing. The proposed listings are the first substances added under the Labor Code mechanism since June 12, 2009, when OEHHA added 30 chemicals. On March 4, 2011, OEHHA stated that three of the four substances proposed for listing (ethanol in alcoholic beverages, leather dust and salted fish, Chinese-style) have been identified by IARC as Group 1 (the agent is carcinogenic to
“
The availability and use of this listing mechanism sets a dangerous precedent.
humans) and the fourth substance proposed for listing (Cyclopenta[cd]pyrene) is identified by IARC as Group 2A (probably carcinogenic to humans). In comments regarding its June 2009 proposed listings, concerns had been raised that OEHHA could propose to list chemicals under the Prop 65 Labor Code mechanism that have not been determined carcinogenic. Here’s how: IARC identified a substance as Group 2B (possibly carcinogenic to humans), even though under that categorization IARC could designate a substance based on insufficient evidence of carcinogenicity in humans or experimental animals and that lack of evidentiary sufficiency would not support a listing decision via the authoritative body mechanism under Prop 65.
”
Discussion The availability and use of this listing mechanism sets a dangerous precedent. Because of the ease with which chemicals can be listed, this mechanism could easily become the mechanism of choice. It also seems premature to rely on this mechanism until the judicial appeal process has run its course. PE

Plant-Wide CONT Pre-selection provides integrated control and power system for improved efficiency, control, monitoring and reporting.
By ROCKWELL AUTOMATION
h river town of Kingston, he O Ontario, sits at the crossroads o of the world’s largest freshwatter system. In one direction: tthe extreme northeast corner of Lake Ontario, the mouth of the Great Lakes. The opposite way: the beginning of the St. Lawrence River, which ends in the Atlantic Ocean. Utilities Kingston, owned by the city, provides asset management, billing, and operational services to utilities in the water and wastewater, natural gas, and electricity industries. The $103 million (Canadian) expansion of the Ravensview Wastewater Treatment Plant (WWTP), located on the shores of the St. Lawrence River, used state-of-the-

art equipment and implemented several best practices that plant managers see as a model for municipalities worldwide. By making the plant as efficient as possible, the utility helps protect the Great Lakes/St. Lawrence basin and communities downstream. “The city of Kingston aims to become the most sustainable city in Canada, and Utilities Kingston has contributed to this goal in a major way,” said Jim Keech, the utility’s CEO. In 2009 the design engineers completed an upgrade of the existing 50-year-old water pollution control plant from primary treatment to secondary biological treatment with one of North America’s largest
biological aerated filter (BAF) installations. It increased average daily capacity by 30 percent, from 72,800 cubic meters per day to 95,000 cubic meters per day. Implementing a plant-wide integrated control and power system designed by Rockwell Automation helped streamline and standardize plantwide control, and contributed to completing the project under budget and six months ahead of schedule.
Challenge The goals for the WWTP were to increase effluent capacity; to improve effluent air and water quality; to reduce noise; and to provide superior biosolids handling, energy savings and efficiency.
Plant-Wide CONTROL
ROL The biosolids handling system produced a product that meets specifications for land applications.
From past experience, the engineers found that control platforms with multiple disciplines were difficult to integrate, scale and coordinate. “If we had multiple MRO [maintenance, repair and operations] systems, we would then have to rely on contractors, who would then have to rely on third-party suppliers – and that adds significant costs to us,” said Allen Lucas, utilities engineer and project manager for the WWTP upgrades. The variation in gear also made it difficult to assemble tender documents for the contractor bids. They wanted to find a better way to choose suppliers, manage the risk associated with startup and commissioning cycles, and improve maintenance and troubleshooting procedures.
“As the lead electrical engineer for the project, one of my major concerns is that we meet all the ministry requirements for environmental reporting and compliance,” said Louis Fournier, assistant chief electrical engineer at J.L. Richards, the engineering company working with the consultant. The plan was to achieve better process and motor control, monitoring, diagnostic and remote access capabilities, improve safety and reduce maintenance. An integrated system would upgrade monitoring and reporting to help meet stringent water industry regulatory compliance demands. The existing plant was a patchwork of various suppliers’ equipment, based on open specifications and low-cost bids.
Solutions
not just the up-front capital costs,” said CEO Keech. In the municipal market, pre-selection of process equipment allows the owner and design team to competitively select a supplier and tailor the design to the specific process. A defined specification and a weighted system based on operations, performance, maintenance, safety and financial aspects, is the key to quality-based selection, but it also takes into account other benefits. “Above and beyond the obvious review of the proposed components,” said Lucas, “a significant portion of the evaluation was based on suppliers’ references, experience, proposal clarity, impressions during the full-day demonstration and interview, and their field services and factory acceptance plan.”
Working together, the engineering companies found suppliers to partner with for pre-approved equipment to meet specified criteria and deliver the best long-term value. “We put out a pre-selection package for motor control centers and controllers, and went out to various suppliers looking for not just equipment but a solution that included partnering with suppliers and integrating the technology from a top to bottom approach,” said Lucas. Lucas saw a streamlined design and bidding process as presenting a clear understanding of the features that are most important, and leading to competitive pricing. “We tried to focus on the long-term lifecycle costs and overall sustainability,

Plant-Wide CONTROL
Above is a typical control screen that provides operators with realtime information on the operation of plant systems. The operator can take actions as needed or schedule required maintenance before a breakdown can occur.
The engineering consultants chose an automation process that included programmable automation controllers (PACs), intelligent motor control centers (MCCs) and variable frequency drives, as well as field services including phone and online support. “We pre-selected the MCCs and PACs together because they are the nerve center of the project and we wanted to take MCCs and starters out of the tender document where they are often treated as commodities similar to nuts and bolts,” said Fournier. “Our experience has shown that the integration of the components can often delay a project or in many cases leave a very unhappy client.” The supplier integrated all of the process operations, controls and motor controls into one system. The process used networking architecture technologies Ethernet and DeviceNet. Ethernet provided the computer networking infrastructure, replacing conduits and wires for each I/O to help reduce wiring and
installation costs. Real-time monitoring was provided using Allen-Bradley PACs installed across the plant. The primary effluent pumps, centrifuges, sludge pumps, chain and flight sludge collectors, blowers, compactors, and HVAC equipment were given motor control centers and variable frequency drives. A solid-state motor control soft starter was installed on the blowers to provide intelligence, advanced protection, diagnostics and communication. It included an integrated bypass to minimize heat generation during run time; the bypass automatically closes when the motor reaches its nominal speed, resulting in a cooler-running component and compact enclosure. Also integrated into the plant’s system were the AC drives to provide improved process control. The drives were meant to provide additional process information from the drive level and automatically disperse it to any part of the plant through the architecture.

Plant-Wide CONTROL To measure and provide power quality reports, engineers installed power monitors on each MCC, each service entrance and each generator. Their purpose was to perform real-time power monitoring, data and event logs, harmonics analysis, sag and surge detection and load factor calculation. The compact power quality and sub-metering monitor would leverage the DeviceNet networks without the need for cumbersome serial interface bridges.
According to Fournier, project milestones that are missed due to unexpected technology integration and start-up issues can cause delays that are calculated at approximately $80,000 per day. The system integrator who assisted in startup and commissioning of the complex network
was trained on the plant-wide automation system. Using one plant-wide control system simplified training, saved time and facilitated troubleshooting. “The week that the integrator spent training at the supplier would have easily taken four weeks on site,” said Fournier.
Vanton solid thermoplastic pumps to stainless, high alloy, plastic-lined and fiberglass pumps for wastewater and corrosive treatment chemicals:
Methane is captured from the operation and piped over the roofs to provide energy where needed.
Engineers also installed condition monitoring with online continuous protection. The intelligent I/O modules process in real-time the critical parameters used to assess the current health and predict future health of the process machinery. Maintenance personnel can use this to develop optimized maintenance schedules based upon the actual or predicted condition of the assets. The team believed predictive maintenance to be a well-proven strategy that can significantly reduce maintenance costs and downtime while improving MRO spares management.

Plant-Wide CONTROL “Trying to sort out communication issues on site typically slows down the process.” Engineers and the system integrator attended the FAT, which took less than two days. Intelligent motor control also helped reduce installation and commissioning time. In addition to the reduced time required for the contractor to install, terminate, label and verify the various I/O points required in a conventional starter, the system integrator was able to verify the operations of an entire MCC in a few hours. The new process automation system helped design engineers go beyond environmental impact concerns and regulatory compliance. While increasing capacity by 30 percent, the plant decreased environmental impact, improved air and water quality, decrease odor, noise, air pollution and energy consumption, and excellent biosolids handling and efficiency. Only two additional staff were required to manage all the new equipment and operations and maintenance requirements.
In 2009, engineers from Utilities Kingston completed installation of the largest biological aerated filtration system in North America.
“The upgrades have helped us take waste and convert it into three beneficial products: clean water, methane gas for power generation and biosolids for land application,” said Lucas, “and we’re doing it in an environmentally friendly way.” The new primary digester has thermophilic operation capability, running at 55°C instead of the required 37°C, which exceeds current biosolids management requirements in Ontario. The increased methane gas produced in the digestion process is used as fuel for a cogeneration
unit, which produces heat and electricity for use on-site. The plant operates at about 1,200 kW with the cogeneration providing approximately 350 kW of that demand. The variable frequency drives improved pump and process control, leading to improved effluent quality.

The upgrade has reduced the five-day carbonaceous biological oxygen demand and suspended solids from an average monthly concentration approaching 25 mg/L to an average monthly concentration below 5 mg/L. The change from using only ferric chloride for removal of phosphorus to relying on the biological uptake in the BAF has resulted in a significant reduction of chemical addition. The design engineers report an overall 75- to 80-percent reduction in ferric chloride added and estimated 20 percent reduction in sodium hypochlorite for disinfection. “A centralized control system helps reduce our overall operations and maintenance costs by providing faster response time,” said Lucas. “An operator can come in and get right on the problem and resolve the issue.” The plant now keeps processes running with minimal human intervention by working efficiently together and reacting to inputs from other machines.

GREENCONNECTIONS By Barbara Quinn
Continual Improvement in Energy Performance Energy efficiency is one of the most powerful tools in controlling global energy use and carbon emissions. y the end of this year, the International Standards Organization (ISO) plans to release a new Energy Management Standard (ISO 50001) to create a framework for managing energy. ISO 50001 represents the work of 54 countries that participated in the development of the standard, which still requires a majority vote by the full ISO before it is approved and released. ISO 50001 is also one of the core elements of Superior Energy Performance (SEP), a certification program that was developed under guidance from the U.S. Council for Energy-Efficient Manufacturing (U.S. CEEM). The goal that U.S. CEEM set is straightforward and assertive: to position U.S. industry as a global leader in energy efficiency and greenhouse gas emissions reduction. The ambition of the organization is not surprising given its membership. The council is a coalition of standard-making organizations including the American National Standards Institute; federal agencies including DOE, EPA and the Department of Commerce; national labs and universities; Texas Industries of the Future – and more than a dozen energy-intensive U.S. industrial companies including DuPont, HP, Dow Chemical, 3M and Alcoa. SEP and ISO 50001 will work cooperatively for companies. ISO 50001 provides a standard framework for companies to set policies and procedures for their energy use. It is a starting point for SEP, which enables companies to verify energy performance improvements and management practices. Both systems grow from the simple premise that energy efficiency is one of the most powerful tools in controlling global energy use and carbon emissions. That same premise is reflected in Dow Chemical’s recent decision to invest $100 million in projects with the greatest impact in performance areas, including reduced energy use and greenhouse emissions along with accelerated cost savings. The money will be awarded to the company’s business units and manufacturing plants with the best proposals for meeting those objectives. The proposals came quickly: within a month of the announcement more than 60 projects had been proposed, representing a potential savings of some $500

The newly certified Texas companies are Cook Composites and Polymers Co. (Houston), Freescale Semiconductor Inc. (Austin), and Owens Corning (Waxahachie). All three demonstrated that energy savings are available, accessible and cost effective. PE

CHOOSING THE RIGHT
HAP OR VOC CONTROL
How thermal oxidation can increase the sustainability of a chemical plant. By JON HOMMES, ENGINEER, DURR SYSTEMS INC.
nstalling new production processes, or upgrading and expanding existing lines today requires a review of the expected emissions. The right emission control system for hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) can efficiently and economically help dispose of these environmentally hazardous wastes. Over the last 20 years, as emission limits have tightened and authorities have taken a more holistic, plant-wide approach to air permits, the trend in the chemical process industry has been to collect multiple waste streams plant wide for control with a single thermal oxidation system, despite the required additional source ducting and piping. This trend has been driven by an array of factors, including: • Rising fossil fuel prices

• Tightening emission limits for VOCs, HAPs, NOX and CO • Goals for reducing a plant’s carbon footprint • Increasing disposal cost of organic waste liquids • Minimizing the number of control systems to be maintained and points of emission monitoring and testing These are key considerations for companies increasingly committed to energy efficient, sustainable production. The benefits of a single, centralized thermal oxidation system can be best illustrated with a case study of a plant that recently added emission controls to multiple existing production processes. Two types of thermal oxidizers are more frequently applied in the chemical process industry: regenerative thermal oxidizers (RTOs) and direct-fired thermal oxidiz-

ers (DFTOs), also known as afterburners. RTOs offer high thermal efficiency and very low fuel requirements for plants that generate dilute air streams contaminated with low concentrations of VOCs and HAPs. However, a DFTO is the best choice when: • Production processes demand steam energy • Required destruction efficiency is greater than 99.5 percent • Highly caloric off-gases with low oxygen must be handled • High loading of halogenated or sulfurous compounds are expected (acid generators) • Destruction of waste liquids is needed Many excellent guides and articles address the selection process between different types of oxidizers. This article focuses exclusively on the DFTO.
CHOOSING THE RIGHT
HAP OR VOC CONTROL
A case in point A company manufacturing organic intermediates for the pharmaceutical and fertilizers industry decided to install a DFTO system to handle all liquid and gaseous waste streams from their small to midsize process reactors and storage tank vents. The DFTO was designed to handle a wide range of wastes, including organic compounds containing halogens, sulfur and nitrogen. The system consisted of the required liquid pipe trains and storage tanks, process off-gas pipe trains, including explosion protection equipment, oxidation chamber, fire tube waste heat steam boiler, and economizer. There was also a scrubber for acid gas removal, selective catalytic reduction (SCR) system for NOX removal, an induced draft system fan and stack, including an emission monitoring system.
Waste liquids and off-gas sources The liquid wastes are accumulated from a number of sources across the plant. The

small storage tank was sized to accommodate the effluents from periodic tank cleaning processes. At this particular plant, all of the waste liquids are purely organic and have a consistent high caloric value, which allows them to be directly fired through the thermal oxidizer’s dual fuel burner system. After startup, these systems can run entirely on the waste liquid fuel.
Although not needed at this facility, a second system is sometimes used to collect liquid wastes with low or inconsistent caloric value or high water content. These wastes are atomized into the oxidation chamber adjacent to the burner through secondary injection lances. In addition to the liquid wastes, a total of six process off-gas streams are con-

trolled by the thermal oxidizer system. Each off gas is handled by an independent control train and separately injected into the oxidation chamber. One stream is drawn from nitrogen-blanketed storage tanks using a blower, designed to handle potentially explosive gases, to maintain a slight negative pressure. The remaining
streams come from process reactors under pressure and can be routed to the oxidation chamber without blowers. The volume of caloric content of each stream is highly variable, especially for several batch reactors and for the storage tanks that vent the most VOC during filling operations. These large variations in flow and loading

lead to the first major benefit of a single, centralized DFTO system. During preliminary engineering of the emission controls, consideration was given to multiple, smaller DFTO systems installed local to each process gas source. This arrangement had the advantage of minimizing the cost of the collection ductwork. However, as the off-gas sources were analyzed, it was determined that each DFTO would need to be designed for the peak gas volume and caloric content required for that source under startup or upset conditions, resulting in large oxidizer size. Furthermore, the much lower so-called “normal” off-gas flow would then be difficult to efficiently handle in the large oxidizer. Bringing all the off-gas streams into a single, centralized DFTO made it possible to design for peak VOC loading on several, but not necessarily all, processes simultaneously, reducing overall system size and capital cost, while improving turndown and DFTO efficiency under normal operation. The availability of the organic waste liquids to the centralized DFTO also had a stabilizing effect on operation, as the storage tank allowed injection of liquids to cease during periods of maximum off-gas loading (while collection in the tank continued), and to resume providing supplemental heat during periods of low off-gas loading. The overall impact of the centralized DFTO was a significant reduction in natu-

ral gas (or other supplemental fuel) usage and thus the plant’s utility budget as well as a corresponding reduction in the plant’s carbon footprint.
Process steam Many chemical plants generate and use steam on site for various process and heating requirements. The flue gas from a DFTO oxidation chamber is a source of high-quality waste heat at 1,600 to 2,200°F.
Diagram of a Selective Catalytic Reduction (SCR) system for NOX control.
Numerous considerations affect the boiler design and selection including: • The desired steam pressure • Requirement for superheated steam • Presence of halogens or sulfur that generate acid gases • The presence of silicon, phosphorous, metals or other dust-forming compounds. In this case, the system included a fire tube waste-heat boiler to generate medium pressure saturated steam, followed by a superheater and an economizer for preheating boiler feed water. High concentrations of HCl and HBr acid in the oxidizer flue gas resulted in a design that limited the heat recovery in the economizer to keep the outlet temperature above the acid dew point under all operating scenarios. In addition, due to the distance from the facility’s main boiler house, the system included a boiler feed water tank with redundant pumps and a de-aerator for returning condensate. Once again, a single, centralized DFTO when compared to multiple local units was significantly more beneficial. To achieve the same steam production, the capital cost was much lower for a single waste heat boiler system with high utilization.
This was because waste heat boilers for localized DFTOs must be designed and sized for the peak flow and heat load from each oxidizer, but will normally operate at just a fraction of that design capacity. It is obvious that the boilers themselves are capital-intensive, but a single centralized waste-heat boiler also minimizes installation costs associated
with piping for boiler feed water, steam supply and blow down. The number of boiler startup and shutdown cycles is reduced, increasing the longevity of the equipment, and minimizing the time demands on boiler operators. By choosing to recover waste heat, the plant further reduced overall fossil fuel consumption and carbon footprint.
The biggest innovation in degassing is really very small. Simplified logistics, faster service and lower costs for degassing. Global Vapor Control is a big idea in a small package. We use portable thermal oxidizer units for best-in-class degassing and VOC/Odor control. Fast-acting Zyme-Flow® chemistry is safe, biodegradable and cost efficient. And we require only a minimum of personnel on-site. Which means, we need less to get the job done more effectively. It all adds up to simplified logistics, faster service, and safer operation while complying with the industry’s most rigorous safety and regulatory requirements.

Acid scrubber After exiting the economizer, the flue gas is directed to a quench and acid scrubber. The quench cools and saturates the flue gas stream with water spray nozzles and flooded walls. The quench discharges the flue gas and water into the base of a vertical flow, packed column scrubber where HCl, Cl2, HBr, Br2, HF and SO 2 are absorbed and neutralized with a NaOH solution. The scrubber was over 99 percent efficient, however, taller columns and multiple stages can be used to achieve greater than 99.9 percent removal. The waste liquid and three of the six off-gas streams currently contain halogens requiring scrubbing downstream of the oxidizer, with the vast majority coming from methylene chloride in the waste liquid. Prior to installation of the new DFTO system, these halogenated liquids were transferred to tanker trucks and disposed of off site at significant expense ($0.20 to $0.50 per gallon).
Typical quench and acid scrubber after a DFTO.
Selective catalytic reduction of NOX Regulatory authorities have focused more and more on reducing NOX emissions from combustion processes, and oxidizers are no exception. In the case of a boiler or process heater, the majority of NOX emissions form as thermal NOX
from N2 in the flame front of gas and oil-fired burners. In the case under study here, the vast majority of the expected NOX came from the oxidation of amines and other VOCs containing nitrogen in the plants off-gases and waste liquids. Several alternative approaches for NOX reduction were evaluated, including non-catalytic reduction in the oxidation chamber, before selective catalytic reduction (SCR) was selected based on the high conversion efficiency required to meet the very low emission targets. SCR also offered the advantage that the catalyst used to reduce NOX favors the destruction of trace dioxins and furans formed during the oxidation of chlorinated compounds. Because the flue gas exiting the scrubber was saturated and contained trace acids, the SCR system began with a pre-heater module to raise the flue gas temperature above its dew point by mixing a small volume of hot air recirculated from downstream.

was constructed in alloys resistant to chloride corrosion. The DFTO system’s redundant draft fans followed the preheater, to be operated with variable frequency drives to maintain a pressure in the oxidation chamber slightly negative to atmosphere. The flue gas then enters a recuperative heat exchanger that recovers heat from the SCR outlet (the reduction process is exothermic) to bring the flue gas up to reduction temperature. Finally, an aqueous ammonia reducing agent is sprayed into the stream, metered precisely to match the measured incoming NOX, before the flue gas enters the catalyst beds where greater than 95 percent of the NOX is converted to N2 and H2O. The flue gas then passes through the other side of the heat exchanger on its way to the system stack, where it exhausts to atmosphere at about 200°F. Continuous emissions monitoring equipment in the stack, as required by the plant’s air permit, tracks exhaust concentrations of total hydrocarbon, HCl and NOX to confirm proper operation of the system. The low NOX emission required for this system was another factor in the selection of a single, centralized DFTO system over multiple systems. The SCR system is capital intensive, including an expensive precious metal catalyst, heat exchanger, and flue gas analyzers and strongly favored installing just one.
Conclusion For this manufacturer of organic chemicals, a single centralized thermal oxidizer system was the most cost-effective path to expand production while meeting new emission controls requirements. The resulting DFTO system benefited them by: • Maximizing the destruction efficiency of VOCs and HAPs • Reducing NOX emissions • Eliminating operating expenses for off site waste liquid disposal • Reducing plant-wide fossil fuel demand by using the caloric value of their wastes to generate steam • Minimizing maintenance costs by installing just one system
Taken all together, the plant’s annual savings actually exceed the operating costs of their new emission control system. Over its design life, the DFTO system provides a net pay back to the plant, proving that “being green” does not have to come at the expense of the bottom line. PE

lbert Einstein once paraphrased an old Chinese saying when he wrote, “What does a fish know about the water in which he swims all his life?” The same could be said of most aspects of our lives, including the air that we breathe. Each day we send our children to school and go off to work without giving a second thought about the air quality of the buildings in which we spend most of our time. We trust others with our health and the health of our children and loved ones. We hope the schools are doing their best to maintain a clean, germ-free environment, wiping and disinfecting everything in the path of the common cold and viral infections.

The right equipment was needed when proper control of a cooling system required repair to ensure that inhalable airborne particles could be controlled. rial and viral infections, facilities managers and building superintendants are also concerned about sources of serious airborne illnesses, including Legionnaires disease. The Centers for Disease Control and Prevention (CDC) estimates Legionnaires hospitalizes 8,000 to 18,000 people each year.
‘Cool’ kids don’t get sick Because of the ever-increasing cost of energy, cooling towers are one of the more widely used, cost efficient means of controlling the climate in large buildings. Properly functioning cooling tower systems save the property management – or in the case of a school, the taxpayer – a lot of money. Water is readily available and comparatively inexpensive. There are many factors that contribute to the proper operation of a cooling tower’s water treatment system. The quality of the water used to operate the system is of the utmost importance. If the water used to operate the system is sufficiently pure, the cooling tower will provide several
years of worry-free service. But pure water does not exist in nature, and impurities can widely vary at each location. Water must be treated to remove contaminates that can threaten the operation of a cooling tower. Scale and corrosion form in cooling towers as a result of such contaminates. Either can foul the operation of a cooling system, lessening the efficacy and cost-effectiveness of the system, and possibly creating the opportune condition for microbiological bacteria to grow and multiply. Luckily this is not a responsibility facility managers have to handle alone. Facilities management personnel often work with water treatment experts to monitor and treat cooling tower water sources within their premises. Water treatment professionals test the water onsite and develop ongoing treatment plans specific to the conditions at the facility to prolong the life of the cooling system, and to maintain the air and water quality standards patrons expect. Chad Brown, vice president of Water

Treatment Services Company, Alexander, Ark., is a 10-year veteran of the water treatment industry. “Our customers all have the same goal: A reliable cooling system that provides a healthy, comfortable environment for patrons and years of cost-effective operation. Customers contact us during many different stages. Architects will contact us to design water treatment systems to be incorporated into the design of new buildings. Facilities managers contact us to help maintain existing cooling tower water treatment systems, and sometimes, unfortunately, we’re called in after a system has lost efficiency or has completely failed,” Brown said. Scale formation in fouled systems is treatable and most times even reversible with the assistance of an HVAC contractor, but repairing and treating the problem after-the-fact can prove to be a costly endeavor for the facility. Brown estimates that de-scaling and repairing a system can cost tens of thousands of dollars, depending on the size of the system and the severity of the scaling.
Educating the school district The Fort Bend Independent School District, Sugar Land, Texas, was introduced to the water treatment company by a satisfied customer’s referral. “Our first experience with the district was at Dulles High School. The mechanical services contractor responsible for the school district contacted Mr, Brown on the recommendation of a colleague, and said that the situation was ‘pretty bad out there.’ They literally had water pouring out of the cooling tower onto the ground, because there was so much scale in the fill.” Upon arrival, the treatment company confirmed that things were bad at Dulles High. “With that amount of scale, it was clear the water treatment chemistry was not correct, and the system efficiency was suffering,” said Brown. “Scale acts as insulation between the water and the metal of the basin, which cools the water. The system was working harder than it should to cool the water because there was no

contact between the two.” Besides the loss of system efficiency and the flooding caused by the scale buildup there was a safety concern. The school was utilizing a traditional liquid chemical program that included 55-gallon drums of hazardous treatment chemicals. Each drum weighed nearly 500 pounds. For the people whose job it is to maintain the system, the program posed both chemical exposure and ergonomic health threats. “The Fort Bend Mechanical contractors indicated that they needed a water treatment system that would perform. They needed a system that was safe for the people who maintained it by reducing employees’ exposure to safety hazards, and that also reversed existing damage, and inhibited new scale formation. After our initial investigation and series of water tests, we determined a solid chemistry program would be the most effective solution,” said Brown.

Chemistry a major bummer Hydro Systems Co., Cincinnati, supplies proportioning, dosing and dispensing systems for concentrated chemicals. The company has developed a series of water treatment systems designed to ensure efficient, safe and reliable operation of the equipment at many stages of the coolingtower water treatment process. “Solid chemical feeders eliminate the personal risk associated with handling the large drums of chemicals. Solid chemical chemistry contains less active chemical when dissolved. Also, the solid chemical containers weigh an average of nine to 10 pounds, and can be easily handled by one person, which alleviated many of the safety concerns [the school district] had with their previous program,” said Brown. “In our industry, a cooling tower water temperature drop of two to three degrees in the first month would be considered a success,” said Brown. “Within two weeks of implementing the

new treatment program at Dulles, the approach water temperature dropped six degrees! Lower water temperatures mean increased efficiency – the system doesn’t have to work as hard to cool the water.” Brown noted that since the program switch, the water treatment company has continually monitored the school cooling tower, and the results are outstanding. He indicated that the testing has shown the approach water temperature falling even farther, and predicts it will settle around 12 to 15
degrees lower, which will equate to a 12- to 15-percent reduction in energy required to operate the cooling system. Looking ahead, Brown is anticipating a long-standing relationship among all involved parties, “The school district has made plans to switch the remaining 50 cooling towers throughout the district to the solid chemistry water treatment program in 2011. We plan to use the solid chemical dissolvers in those buildings, as well. They work, and work well. They did exactly what we needed them to do.” The absence of scale and corrosion means the absence of opportunity for troublesome microbiological contaminants, such as Legionella, to grow. At the Fort Bend Independent School District, these absences will certainly be excused.

Recent research1 indicates the vinyl chloride reductase (vcrA) gene is the best predictor of complete dechlorination of PCE and TCE to ethene. It’s simple, other dechlorination genes are just less common in the environment. Testing for vcrA, provides maximum confidence your site has the “Right Stuff” for successful bioremediation. SiREM’s test for vcrA is called Gene-Trac® VC. SiREM is the only laboratory authorized to test for vcrA through an exclusive license agreement with Stanford University*.

The Hydrotron wet dust collection system shown above can be custom fit to improve workflow and provide worker safety.
Wet dust filters not only ensure regulatory compliance but can also improve worker comfort and production flow. otentially explosive dust from metal finishing operations can be a major concern among fabricators, not only due to the potential safety hazards but because recent changes in National Fire Protection Association (NFPA) regulations have toughened compliance. Grinding and sanding metalwork pieces can produce fine metallic dust that – even after filtration – could be exposed to sparks and result in smoldering, catching fire or even an explosion in circumstances when ordinary dry dust collection methods are used. The situation can become even more hazardous when the dust from certain metals is mixed in a dry collection system. Mixing aluminum and steel dust, for example, is an accident waiting to happen.
P
Combustible metals that are common in manufacturing and machining operations include aluminum, lithium, magnesium, niobium, tantalum, titanium, zirconium and even cold-rolled steel. By switching to wet collectors many companies are upgrading their protection against dust fires and also improving air quality for workers. Some wet collection systems can be customized to improve ergonomics for workers by positioning work pieces at more comfortable levels, or facilitating access of hoisting equipment that eliminates the need of workers to lift heavy items. Such improvements may also lead to improved production flow. Wet dust collection units filter explosive dust directly into water in-plant, thus eliminating a potential hazard site at the duct. These devices comply with federal
regulations (NFPA and OSHA) without interfering with manufacturing processes. “We switched most of our dry dust collectors to wet ones,” said Terry Graham, equipment engineering specialist at Bell Helicopter, Fort Worth, Texas. “Because we work with a variety of materials, including metals like steel, titanium, magnesium and aluminum, the wet collectors will improve our protection against any smoldering material or fire.” Graham said his plant has two major machine centers, one has six stations and the other has eight. Most of them have now been outfitted with downdraft wet collectors from Filter 1, Garland, Texas.

Products and Engineering (MPE), a Milwaukee-based designer and fabricator of enclosures, carts and consoles used by the medical and electronics industries, decided to take a new look at its dust collection system requirements. The main dust concern at MPE was handling systems that generated fine dust during the metal finishing (grinding and sanding) of regular cold rolled steel. Due to the more hazardous situation of combining dust from aluminum grinding with that from steel, the aluminum metal finishing area was located in a completely separate part of the shop. “The steel that we’re grinding turns into a form much like steel wool lint,” said Teresa Stortz, MPE process improvement engineer. “The hazard occurs when that lint is hit by grinder sparks, it could smolder and ignite. Of course that is a situation that we absolutely must prevent. In addition, we want remove as much of the very small dust particulate from the air as is possible and these units seem more than capable of helping us on both fronts.” “We wanted to replace existing dust collection systems because of shop-wide air quality,” said Stortz. “But we didn’t have any preconceived notions or specifications about what kind of system we should get. So I was surprised and reassured when the president of this company, who is a filtration engineer, visited our company to see our application firsthand.” The supplier loaned the company wet collectors of the design that the engineers felt would likely suffice for the application so they could evaluate performance. The specified system cleans the air through a combination of centrifugal force and violent mixing of water with contaminated air. As the air stream passes the fixed baffles, particulate is separated by a heavy, turbulent curtain of water created by high velocity air. The centrifugal force caused by the rapid changes in airflow direction forces the dust particles to penetrate the water droplets and become entrapped. Contaminated water is then removed from the airstream by special mist filters. Dust, as sludge, settles to the collector bottom, and the water is reused. The company chose to install seven

wet downdraft tables. “That has helped us tremendously, and no other supplier offered to give us trial equipment,” said Stortz. “The units they suggested we try, downdraft table designs, worked very well. The operators loved them.”
Customizing for comfort and productivity Many industrial applications are better served by a customized dust collection system, rather than an off-the-shelf model. Popular custom design elements include making systems fit into tight spaces, or integrating special features such as a crane slot, adjustable up-and-down tables, multiple hoppers and wet spark traps. A choice of fan designs may also be important to optimizing performance and improving energy efficiency in applications with high-pressure requirements. Stortz said that the new dust collection system also gives them the ability to build in equipment that increases the safety of handling the products their operators and technicians are working on. “The parts can get fairly large, weighing in excess of 100 lbs. We’ve designed the equipment and area so that each operator would have lift-assist equipment available at his or her workstation. This will improve worker safety as well as increase productivity.”
WET DUST
is Safe Dust
“I believe these new wet collectors improve the working environment for employees who occupy these machine stations,” said Graham. “There have been ergonomic improvements with the wet collection systems. The units are configured so that the work surfaces are more in the worker’s power zone. Where there are stations that work on heavy parts, the filters have slots so that the crane can move a part inside the booth and load the part on the table. The improved ergonomics benefit seems to speed up production and also help employee morale as well as making it less likely that workers will be off due to an injury.”
Mixed dust applications David Creaser at Elite Manufacturing Technologies Inc. Bloomingdale, Ill., a sheet metal fabricator, said his company
recently installed a 30-foot-long wet control booth to facilitate the safe collection of metal dust from the company’s grinding operation.
Creaser said that in the process of researching the most effective form of dust collector, he realized that the only type that would enable his enterprise to work
“
The supplier loaned the company wet collectors of the design that the engineers felt would likely suffice for the application so they could evaluate performance.
“We work in a variety of metals, including steel, galvanized stainless and aluminum, for example,” said Creaser. “We decided on the wet type of collection booth for our grinding operation primarily because of the hazards that can come from the dust from dissimilar metals, particularly aluminum and stainless steel.”
”

Product Focus: Sampling/Analysis Equipment Passive VOC Air Sampling The company announced its Waterloo Membrane Sampler used to monitor VOC vapor is now available. It uses a polydimethylsiloxance membrane across the face of a vial filled with a sorbent medium. VOC vapors partition into and permeate the membrane. The uptake rate has been tested for many common VOCs and can easily be calculated for other compounds that are directly proportional to the retention index, as the values are readily available in standard scientific literature.
Smarter Gas Detectors The TA-2100 RS485/4-20 mA 3- or 4-wire gas detector can detect hundreds of gases utilizing several sensor technologies such as electrochemical, infrared, catalytic, photo-ionization and more. The company claims the sensors and detection technology used by the detector eliminates false alarms. Industries such as chemical plants, steel mills, oil & gas, water & wastewater treatment, air quality monitoring, pulp & paper mills, laboratories, pharmaceuticals, tanker ships & vessels, and any other industry where harmful gases are present will have use for such an instrument.

Dart Scores a Bullseye The Dart system aids identification of petroleum, coal tar or creosote nonaqueous phase liquids (NAPLs) in sediments and soft soils. The system can be deployed where mechanized soil-boring techniques are not practical or feasible. The samplers are fiberglass rods coated with solid-phase extraction (SPE) media. When a site, shoreline, or sediment under an adjacent water body might be contaminated, the rods are inserted by hand, slide hammer or extension pole. Over a 24- to 48-hour period, the SPE coating sorbs any existing polycyclic aromatic hydrocarbons (PAHs), which are found in petroleum, coal tar and creosote NAPL. The SPE causes the PAH to intensely fluoresce.

Nantucket Sound (APNS) submitted an adverse comment to the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE), which helped scuttle a BOEMRE action intended to expedite leasing of offshore areas for renewable energy development.
NC – PHASE II STORMWATER CONTROLS CT – ENERGY, ENVIRONMENT DEPARTMENT COMBINED In an effort to reduce state costs, Gov. Dannel Malloy has started combining state agencies. The governor’s new Department of Energy and Environment (DEEP) demonstrates such efforts as it consolidates the state’s widely dispersed energy functions, including the Department of Public Utility Control, with the Department of Environmental Protection to allow for a more effective coordination of energy and environmental policies.

The DENR is considering measures for 18 communities in the Lumber and Yadkin Pee-Dee river basins to limit stormwater pollution under federal Phase II stormwater program. Stormwater controls would include eliminating untreated wastewater discharges to creeks, developing campaigns to educate the public, and control requirements for new development.

OR – UNCERTIFIED WOODSTOVES MUST GO
Forty-one towns will be making improvements to municipal buildings to improve energy efficiency and save money. Gov. Jack Markell and DNREC Sec. Collin O’Mara recently announced that the towns will receive federal funds for the improvements as part of the Energy Efficiency and Conservation Block Grant (EECBG) program, which is aimed at reducing the use of energy derived from fossil fuels.
The state’s new woodstove law, designed to protect homebuyers and clear the air of unnecessary wood smoke pollution, requires the removal and decommissioning of any uncertified woodstove or fireplace insert from a home when a property is sold. Although homeowners now are required to remove and destroy an uncertified woodstove, the rule revisions include new requirements regarding notification and destruction requirements.

Facilities in the state will not face greenhouse gas (GHG) emissions permitting restrictions pending
the outcome of the controversy at the federal level. TDEC recently proposed to rescind state GHG permitting rules if federal regulations are vacated.
UT –UPDATED PESTICIDE RULES The state Department of Agriculture and Food recently proposed significant changes to its existing pesticide regulations. The revised rules stem from a tragic 2010 incident that resulted in the death of two children caused by the negligent application of the pesticide Fumitoxin at the residential property. The federal EPA later banned the use of Fumitoxin in residential areas, increased buffer zones from 15 to 100 feet around nonresidential buildings, and created a more protective product labeling.
