摘要： A point-of-use catalytic oxidation system, for treatment of a VOC-containing gas stream, including: a heat exchanger for heat exchange of a VOC-containing gas stream and a VOC-reduced gas stream at higher temperature than the VOC-containing gas stream, for heat recovery from the VOC-reduced gas stream for cooling thereof, to preheat the VOC-containing gas stream; a supplemental heater for supplemental heating of preheated VOC-containing gas, if and as required, to an elevated temperature for catalytic oxidation of VOC therein; and a bed of catalytic oxidizer material for catalytic oxidation of VOC in the VOC-containing gas stream, to yield the VOC-reduced gas stream. The heat exchanger, supplemental heater, and bed of catalytic oxidizer material are sized, constructed, arranged, and operated to effect autothermal catalytic oxidation of VOC in the bed of catalytic oxidizer material. The system may further employ a smoother to attenuate influent VOC spikes in the feed gas, and/or a concentrator to concentrate the feed gas VOC species for high efficiency VOC removal in the catalytic oxidation.
