Abstract
The present invention provides for a process for handling carbonyl sulfide waste and waste metal halides produced in industrial processes and, more particularly chlorination processes. The process includes the steps of hydrolyzing the carbonyl sulfide to produce a waste stream containing hydrogen sulfide and sulfidizing the resulting hydrogen sulfide containing stream with a solution of the waste metal halides. The resulting metal sulfide and metal halide-containing stream can be neutralized before disposal of the produced waste solids.
