| titleOfInvention | Recovery of hydrogen chloride from chlorinated hydrocarbons such as chloromethanes |
| abstract | High purity hydrogen chloride is recovered from a gaseous product stream consisting essentially of hydrogen chloride and at least one chlorinated hydrocarbon of from one to two carbon atoms, such as the chloromethanes, by a process which has significantly lowered refrigeration requirements, thus resulting in savings of energy and materials. The process involves (a) condensing essentially all of the gaseous stream to form a liquid phase feed stream wherein the liquid phase consists essentially of the hydrogen chloride and the chlorinated hydrocarbon(s); (b) passing the condensed liquid phase feed stream to a stripping zone; (c) maintaining the stripping zone at a pressure and temperature profile sufficient to retain essentially all of the chlorinated hydrocarbon(s) in a liquid phase and to allow essentially all of the hydrogen chloride to separate in a vapor phase; (d) removing a first recovery stream consisting of the high purity hydrogen chloride vapor phase from the stripping zone; and (e) removing a second recovery stream consisting of the chlorinated hydrocarbon(s) liquid phase from the stripping zone. In a preferred embodiment the gaseous product stream is from a methyl chloride thermal chlorinator and consists essentially of hydrogen chloride and a chloromethane mixture, this gaseous product stream is completely condensed and cooled to a temperature between about -30° C and about -10° C and then fed to the stripping zone which is maintained at a pressure between about 200 psia and about 250 psia. |
