Patent ID: 7060236

Claim:
A process for continuously removing and destroying volatile organic compounds (VOC) from industrial and commercial effluent consisting steps of: a. packing a fixed bed absorber and a fixed bed regenerator in series with high surface area adsorbent, b. introducing said effluent to said absorber for adsorption of VOC to obtain a clean treated effluent, c. venting part of said clean treated effluent from said absorber to the atmosphere, d. blending part of said clean treated effluent with air to an appropriate level of oxygen to form a regeneration gas, e. bringing said regeneration gas to a takeoff temperature and charging said regeneration gas to said regenerator whose adsorbent is loaded with VOC from previous adsorption cycle, f. converting VOC to innocuous compounds to form hot regenerator exhausting gas for venting to the atmosphere and regenerating said adsorbent, simultaneously, g. switching said absorber to become a regenerator and said regenerator to become an absorber to start a new cycle of operation just before VOC breakthroughs said absorber, whereby said effluent is continuously cleaned of VOC for venting to the atmosphere.
