ABSTRACT:
Chlorinated solvents are removed from vapor vent streams containing the solvent, water and non-condensable vapors by contacting the vent stream with a liquid spray of precooled chlorinated solvent at a temperature less than the freezing point of water. The solid ice floats on the liquid chlorinated solvent and can be readily separated therefrom.
