Process for extracting (chlorinated) hydrocarbon-free hydrogen chloride and phosgene-free (chlorinated) hydrocarbons from a hydrogen chloride stream containing (chlorinated) hydrocarbons and phosgene
摘要：
(Chloro)hydrocarbon-free hydrogen chloride and phosgene-free (chloro)hydrocarbons are recovered from a hydrogen chloride stream having (chloro)hydrocarbons and phosgene. The recovery involves connecting a first adsorber and a second adsorber in series and passing the fresh hydrogen chloride stream comprising phosgene and (chloro)hydrocarbons firstly through the first adsorber and subsequently through the second adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the first adsorber, passing the fresh hydrogen chloride stream through the second adsorber while the first adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration, passing the fresh hydrogen chloride stream firstly through the second adsorber and subsequently through the regenerated first adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the second adsorber, and passing the fresh hydrogen chloride stream through the first adsorber while the second adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration.
