FILTRATION AND CATALYTIC VOC DESTRUCTION

摘要

To help control and reduce the levels of VOC emitted to atmosphere the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme are applying regulatory procedures to reduce VOC emissions from industrial sites. There are several abatement methods available to concerned industries in order to remain compliant with legislation, however, in many instances the chosen method is via capture and/or destruction by incineration. These methods result in high energy costs and further emissions to atmosphere of harmful CO and NO_xX compounds and other pollutants as by-products of inefficient combustion. More recently flameless combustion of VOC's by thermal catalytic conversion to harmless water vapour and low levels of CO2, has proven to be an effective means of reducing levels of VOC in a more environmentally friendly way. FIT-lnfrared Ltd (FIT) has developed a VOC abatement technology based on this process. The FIT VOC abatement process can utilise Zorflex~R activated carbon cloth adsorption technology to produce an efficient regenerable VOC filter. The result being a cost effective, energy efficient and low maintenance process for reducing the carbon footprint of industries associated with VOC emissions. Chemviron Carbon Cloth Division (CCCD), manufacturers of Zorflex~R activated carbon cloth, has worked closely with FIT in the validation of the FIT VOC abatement plant (Indirect Vocure Module) utilising Zorflex~R technology. Zorflex~R proved to be an effective regenerable filter, capturing and releasing VOC's by adsorption and desorption for oxidation by thermal catalytic combustion and reducing VOC level from an industrial automotive spraying plant by up to 81.5%. This brought the emissions from the spraying plant into compliance with local council regulations, hence significantly reducing their carbon footprint.
