Abstract
An integrated process for treating a vent gas stream containing halogenated organic compounds to produce a clean vent gas with vacuum swing adsorption of the halogenated organic compounds and the recycle of a gaseous stream from the halogenated organic compound recovery section. A liquid sponge oil containing halogenated organic compounds is contacted and admixed with the evacuated effluent from the adsorption zone to prevent the accumulation of normally gaseous hydrocarbonaceous compounds.
