ABSTRACT:
The invention is a method for reducing the amount of ethylenically unsaturated chlorinated hydrocarbons in gaseous mixtures. The method comprises providing a gas stream containing the ethylenically unsaturated chlorinated hydrocarbon and ozone by admixing ozone with a gas stream containing ethylenically unsaturated chlorinated hydrocarbons or introducing the ethylenically unsaturated chlorinated hydrocarbons into a gas stream containing ozone, and permitting the gas containing the ethylenically unsaturated chlorinated hydrocarbons and ozone to react for a sufficient length of time to reduce the amount of ethylenically unsaturated chlorinated hydrocarbon in the gas stream. The method is particularly useful for removing small amounts of vinyl chloride from gaseous streams thereby substantially reducing or eliminating the emission of such contaminants into the environment.
