Recuperative system controls plant`s VOC emissions
American Decal and Manufacturing Co., a producer of reflective security films, added a recuperative thermal oxidizer to control volatile emissions. ADM greatly simplified the project by assigning responsibility for system design and construction to a single source. Ross Air Systems, Somerset, NJ, provided a complete package--the oxidizer, capture system, heat recovery system, coater and dryer. The recuperative system passes solvent-laden air through a combustion chamber in which the temperature is increased to as high as 1,500 F, converting the VOCs to carbon dioxide and water. The energy contained in the solvent is released during combustion, and supplemented by burning natural gas to achieve the desired temperature. Control of natural gas firing is automatic, and varies with the solvent loading. Products of combustion existing the chamber then go through a heat exchanger, which preheaters process air, minimizing fuel usage. Further heat recovery provides heated water and heated plant makeup air. The capture system includes an enclosure around the coating area, with fixed and sliding panels to allow installation and removal of coating rolls, floor sweeps to capture solvent fumes that escape initial collection, explosion-proof lighting and safety glass windows, all designed for sufficient operator access.
