Abstract

We developed a new process employing catalytic combustion for textile coating aimed at decreasing emissions of volatile organic compounds (VOCs) and saving energy at the same time. For this purpose, the VOCs are concentrated in a temperature swing adsorption (TSA) device. A fraction of the concentrated VOCs is completely oxidized on an electrically heated (EHC) system, and its combustion gas of EHC is supplied as the heating source via heat exchangers. The remaining concentrated VOC is recycled as a renewable energy source for the drying process to dual-type catalytic burners designed specially to operate with LPG and concentrated VOC at the same time. This system minimizes the problem of VOC emission and maximizes energy conservation by reusing the VOC, toluene, from textile coating.
