Air pollution regulations drive deployment of flexible abatement solutions

is often the case for high flow rates. Thermal oxidation abatement solutions tend to be more economical at very high VOC concentrations whereas catalytic oxidation is typically more economical at moderate VOC concentrations. AirProtekt recognises that no two appli- cations are the same, and each requires careful assessment before a value for money solution can be implemented. For example, although an alternative solution to a catalytic oxidation could be the use of a thermal oxidation system, this may result in high running costs because natural gas would have to be brought into the factory area. A thermal oxidation approach in certain cases can prove inflexible, because if demand dropped the abatement plant would still need to be kept running. A reliable Honeycat Air Pollution Control Systemoffersacatalyticoxidationsolution that provides an expected availability of more than 99% and can be equipped with a superior performance catalyst to reduce environmental emission limits. AirProtekt’s engineering solutions are tailored to address specific local emission requirements but are also specified to

To address the growing complexity of air pollution regulations, which have to address a multi-tiered array of local authority, national and international requirements, AirProtekt of Cambridge, UK, is offering a total package air pollution service that embraces process assessment, project design, supply of the air pollution equipment, installation and commissioning. Many air pollution applications call for flexible abatement systems to be designed and deployed, especially where there is a requirement for batch- based production runs. Low running costs together with the ability to run the abatement at low process flow rates are vital. A quick start up system also offers major benefits. AirProtekt’s flexible package approach to providing engineering solutions means that the company is capable of combining and tailoring modular equipment to meet exacting air pollution requirements in a cost-effective way. For the majority of abatement applications catalytic oxidation is more expensive than thermal oxidation at low flow rates. However, the reverse

comply with national and international regulations as well as detailed global company-specific guidelines or operational procedures. Trevor Lawton, AirProtekt’s managing director said: “Our engineering team often specifies an electrically pre-heated abatement system to provide processors with a very low maintenance solution. We also aim to offer systems that operate quietly to ensure that residential properties are not disturbed.” The industrial air pollution control catalysts favoured by AirProtekt comprise thin-walled honeycomb supports coated with a fine dispersion of Platinum Group Metals, impregnated into a high surface area washcoat. The catalysts, which form the heart of AirProtekt’s catalytic oxidation system, are derived from proven autocatalyst technology and offer benefits that include a long effective life, and the ability to withstand high temperatures. A range of high poison resistance catalyst types are available from AirProtekt, which include a standard VOC oxidation catalyst; a chlorinated VOC catalyst; an LHC catalyst for methane, ethane, propane as well as a sulphur-resistant catalyst. AirProtekt’s systems are also capable of running at low catalyst operating temperatures to minimise running costs and thermal stress.

GRP pipes and fittings GRP pipes from ECE Pipe Systems are produced between DN 300mm and DN 2,800mm, and SN 2500-10,000N/m 2 . The GRP pipes, which are produced with a continuous filament winding process, are widely used in drinking water, sewerage, irrigation networks, hydro-power projects, industrial waste projects and geothermal-cooling water projects. ECE also produces metal reinforced HDPE corrugated pipes and fittings. The MRP pipes produced are between DN 600mm and DN 1,600mm. MRP pipes that are reinforced using steel plates have stiffness classes between SN 4 and SN 20kN/m 2 . The pipes are used in sewerage-storm water networks, septic discharge projects, gutters, cable manhole-highway culvert applications and drainage systems. ECE Group has 25 years’ experience in the production of concrete and reinforced concrete pipes, and has two established factories in Manisa and Adapazarı in Turkey.
