Abstract
An integrated process for vent gas treatment for the abatement of volatile emissions is disclosed. The vent gas comprises dioxygen, carbon monoxide, hydrocarbons and other organic compounds comprising one or more alkyl halide compound of 1 to 5 carbon atoms. In the preferred embodiment, the vent gas is heated and mixed with an amount of combustible fluid. Then the mixture is directed to a catalytic oxidation reactor having a suitable oxidation catalyst disposed therein, wherein the mixture is catalytically oxidized. The effluent from the catalytic oxidation reactor is directed to heat the incoming vent gas and subsequently to a scrubber wherein the effluent is scrubbed of soluble compounds and the resultant treated gas stream is vented. Importantly, the amount of combustible fluid supplied to the vent gas stream is controlled so at to provide sufficient reactants for the catalytic oxidation to maintain reaction temperatures from 200.degree. C. and 600.degree. C.
