  • The Chemical Aspect of NOx Scrubbing

    With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOx (Nitrogen Oxides) produced. NOx is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NOx is produced in a variety of ...

  • Common Treatment Technologies for Halogenated VOCs in Air Emissions/ Off-Gases

    Three technologies that are most commonly used to treat halogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles with a ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Case study - Ice Blast technology for steam generator decontamination

    Background At Point Lepreau NGS the Health Physics Department looked for alternative decontamination methods that could be applied to reduce the dose expenditure as a result of maintenance on the primary side of our steam generators. Due to the characteristics of the CANDU design (i.e., primary circuit being high purity D2O) introduction of foreign contaminants was also a concern. ...

  • Issue highlight: Air Effluent Control RotaBed Scrubber: One way to meet Cluster Rules in the bleach plant case study

    The so-called Cluster Rule promulgated by the US EPA at the end of 1997 seeks to legislate control of both air and water emissions under one, all-encompassing regulation. With proper design and application, Cluster Rule requirements can be met easily and economically on modern kraft bleaching sequences using fluidized bed gas scrubbing technology such as the Rotabed, a product of Bionomic ...

  • Hyperion case study - UVC lights enhance air quality

    Located at the center of the Hyperion Wastewater Treatment Plant in Los Angeles, the Pregerson Building was experiencing indoor air quality (IAQ) problems. Built in 2002 to house nearly 400 city employees, the facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet- C (UVC) lights in ...


  • Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water

    Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other ...

  • Efficient cleaning of effluent gases from optical fibre production processes using a V-tex scrubber

    In this paper we discuss a unique process technology called the V-tex scrubber. Its design makes it particularly suitable for a wide range of scrubbing and stripping applications, where it can deliver economic and technical advantages for the operator versus conventional packed tower or tray scrubbers, venturi and fluidized bed scrubbers. In cases where there are both particulate and gaseous ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Scrubers with a level head

    The available methods for removing pollutants from a gas stream are numerous, to say the least. A popular method, scrubbers allow users to separate gases and solids by allowing the gas to come into contact with a liquid stream. In the end, the pollutants are washed away in the effluent, and the gas exits the system to be used in later processes or to be released into the atmosphere. For many ...
