Abstract: A number of sources in the wastewater treatment process such as the headworks, aeration tanks, settling tanks and dewatering press can produce high-intensity odors from gaseous sulfide emissions. The most common sulfides are hydrogen sulfide and methyl mercaptan. Verantis demonstrates the effectivness of their solution to this problem with an actual real-world demonstration.
Abstract: The objective of any gas-monitoring program is to determine the true subsurface gas regime and predict how this may change in the future. This is currently achieved by discrete periodic static measurements of gas concentrations from which the gas regime is inferred. Contaminated land and landfill industry regulators recognise the need for more representative data but cost has prevented the collection of continuous records of ground-gas measurements. However, the availability of reliable miniature infra-red sensors has recently been combined with innovative engineering to produce a new instrument: GasClam, which will allow the collection of continuous data to become widely used.
Abstract: The environment of the waste stream has been a challenge for most gas monitoring systems. There is high moisture, humidity, poisons and corrosive materials to combat, not to mention the challenge of monitoring for unknown solvents found in the waste stream atmosphere. This white paper explains how continuously monitoring for flammable gases and vapors is the only certain way to guard against these hazards. Because of its unique construction and operating technology, Control Instruments’ PrevEx Flammability Analyzer is the optimum analyzer for this application.

Abstract: Pharmaceutical facilities use a variety of hazardous gases and solvents in their production processes. These substances must be continuously monitored to protect personnel and facilities from accidental releases or leakage. In addition, the pharmaceutical MACT/NESHAP stringently restricts emissions of common solvents and reactants and requires plants to continuously monitor and record compliance status from affected operations. In many cases the primary line of defense in protecting workers and equipment from these atmospheric hazards is a hazardous gas monitoring system. This paper addresses the hazardous gas monitoring technologies available and the most efficient, effective and economical choice for applications in the pharmaceutical plant.
Abstract: Smoke and Dust Emissions in the United States and Canada are regulated through the emission limit values for opacity. Pending regulatory developments would require stationary sources to measure and report particulate mass emissions in place of opacity. With an appropriate choice of analyzer, both opacity and mass concentration can be measured using the same device. Recent developments in monitoring technology, and associated standards published by ASTM International, allow very low levels of opacity to be measured accurately. The limiting factors are the optical performance of the monitor, the characteristics of the installation and the stability of the applicable calibration standards.

Abstract: The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for energy conservation and energy cost reduction. It is no surprise that a wide range of stack energy recovery options have been developed and marketed to end users of oxidizer systems. This article will discuss three important aspects of energy reclamation from hot oxidizer stacks.
Abstract:
Global climate change is a phenomenon that is creating unprecedented business challenges that are being felt from the production floor to the boardroom. Top-line and bottom-line growth can be threatened by new risks while growing interest in corporate eco-efficiency by both consumers and investors is creating new business opportunities. Broad-based interest in the potential impact of global climate change highlights the need for complete, accurate, and comparable data in order to make effective business decisions. The criticality and complexity of the information dictate that a comprehensive information management strategy will be required to address the increasingly critical nature of global climate change.

Abstract:
Over the past decade, a new generation of advanced biofilter systems (bio-oxidation systems) has come to the forefront. These systems incorporate the same basic biological principals as previous systems, and they feature advancements making them much more compatible for industrial applications. For example, the media used now provides increased surface area per unit volume (i.e., more air-to-biofilm contact area) with a substructure that virtually eliminates compaction. These advanced systems are designed to provide the right atmosphere for the microbes (the matter that provides the low temperature bio-oxidation of the contaminants) to do their best work.

Abstract:
Small-scale (less than 20 MW) biomass-fueled power plants offer great potential for low-cost, efficient energy generation. Biomass gasification is a thermal destruction process which produces synthetic gas as an end-result. During gasification, various pollutants may be produced depending on the make-up of the original biomass material. These pollutants can be captured by use of existing air pollution control technologies. A pilot system was developed to evaluate the first phase of the project using wet scrubber and wet electrostatic precipitator technology to control emissions from a biomass gasifier. The results showed that wet scrubbing can be effectively used to control air emission.

Abstract:
An adhesive manufacturing company and Bio·Reaction Industries completed a multi-week pilot study to determine the effectiveness of biofiltration for VOC removal (as determined by Method 25A) from the resin manufacturing operation. This evaluation demonstrates the ability of a bio-oxidation system (biofilter) to meet the requirements of the MON MACT for this chemical manufacturing process (including styrene emissions) as a part of the resin manufacturers group. Physical and chemical conditions associated with the unit were measured, and inlet and outlet air samples taken periodically for VOC removal efficiency.
All data indicated that removal efficiencies of 98% were continuously attainable, meeting the BACT requirements and equaling or exceeding existing permit requirements.
Abstract: Ethanol plant air emissions have emission design considerations that are different from many other such systems. NESTEC Inc. explains just what the differences are and how best to make proper adjustments.
Abstract: Particulates of all sizes, acid gases, caustic gases and more can be effectively cleansed from air emission streams with the Cloud Chamber Scrubber. The physics of electro-fluid technology allow these and other contaminants to be removed at efficiencies that typically exceed 99 percent. Energy requirements are lower than electrostatic precipitators as only 10 watts per 1000 CFM are required to operate the system. This paper provides details and performance information about the system.
Abstract: Low level (3%) maximum allowable opacity emissions limits promulgated by the USEPA, for certain industrial processing industries, have created a compliance dilemma. However, documented evidence questions the ability of opacity dust monitors to operate reliably at opacity levels below 10%. Triboelectric bag leak detectors have proven to be a viable alternative to COMS in low level dust emissions and permission is sought to substitute COMS with triboelectric bag leak detectors, for dust monitoring applications below 10 %.
