CATALYTIC VENT GAS TREATMENT SYSTEM FOR ABATEMENT OF VOLATILE CHEMICAL EMISSIONS

摘要

An integrated process of vent gas treatment for abatement of carbon monoxide and volatile organic compound emissions from achemical process plant is provided, and includes provisions for catalytic oxidation of organic pollutants with dioxygen in a vent gas streamover a solid oxidation catalyst (44), means for supplying an amount of combustible fluid (31) into the vent gas stream upstream of theoxidation to facilitate catalytic oxidation of the organic pollutants; and means for controlling the amount of combustible fluid being suppliedby the supplying means, the controlling means being arranged to provide sufficient reactants for the catalytic oxidation to maintain suitablereaction temperatures in accordance with the present invention.
