<p>In the production of chlorinated hydrocarbons, a waste water stream is recovered from the effluent and stripped of chlorinated hydrocarbon impurities by the use of a portion of the hydrocarbon to be chlorinated as a stripping gas. In addition, an aqueous hydrogen chloride stream recovered from the chlorinated hydrocarbon effluent can also be stripped of chlorinated hydrocarbon impurities by the use of a portion of the hydrocarbon to be chlorinated as a stripping gas.</p> |
