| Zusammenfassung: | Halogenated hydrocarbon and uncontaminated water is recovered from a stream of process water contaminated with halogenated hydrocarbon and hydrogen halide. The process water is neutralized and then distilled to obtain a first fraction containing halogenated hydrocarbon and water and a second fraction containing uncontaminated water. The first fraction is allowed to settle into layers of halogenated hydrocarbon and water which are then removed. The contaminated stream may be obtained from a process for the solvent dewaxing of a petroleum fraction. |
