Abstract
Chlorine-containing organic compounds are reacted with a sulfur-containing stream to produce hydrogen chloride, carbon disulfide, and/or hydrogen sulfide. Hydrogen chloride and carbon disulfide are recovered as products. Hydrogen sulfide is recovered as a product or converted into elemental sulfur for recycle using chlorine or oxygen-containing gas.
Claims8
A process for the treatment of chlorinated hydrocarbons consisting essentially of
- (a) reacting said chlorinated hydrocarbons with a sulfur-containing stream which contains elemental sulfur and hydrogen sulfide in a reactor at temperature between 250.degree. and 1000.degree. C. and pressure between 10 and 700 psia. to obtain a product stream which contains carbon disulfide, hydrogen chloride, hydrogen sulfide, and unreacted sulfur;
- and
- (b) recovering said unreacted sulfur for recycle or disposal, recovering said carbon disulfide as one product, removing said hydrogen chloride for recovery or disposal, and removing said hydrogen sulfide for recycle, disposal, or conversion into elemental sulfur.
