Abstract
In the production of chlorinated hydrocarbons, a gas stream containing unreacted hydrocarbon, carbon dioxide, and chlorinated hydrocarbon(s) is contacted with an acid gas absorption solution to absorb carbon dioxide, with the absorption solution being stripped of any absorbed chlorinated hydrocarbon, preferably by use of feed hydrocarbon as stripping gas, without stripping of carbon dioxide therefrom, to maintain the rich absorption solution introduced into the carbon dioxide stripper essentially free of absorbed chlorinated hydrocarbons.
