Abstract

In the production of chlorinated hydrocarbons, a gas stream, containing hydrocarbon and carbon monoxide and/or nitrogen, as inerts, is separated from the effluent, and contacted with chlorinated hydrocarbon, as an absorption liquid, to absorb unreacted hydrocarbon. The absorbed hydrocarbon is stripped from the solution and recycled to the chlorinated hydrocarbon production. The process is particularly applicable to the production of chlorinated methanes and vinyl chloride.
