Abstract
Vinyl chloride is removed from gas streams that contain from about 10 ppm to 1000 ppm of vinyl chloride by contacting the vinyl chloride in the gas stream with ozone in the presence of activated carbon. The gas streams treated in this way contain less than about 1 ppm of vinyl chloride and no detectable amount of ozone or ozonides.
