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.

摘要： Process for preparing chlorine from hydrogen chloride, which comprises the steps: a) feeding of a stream a1 comprising hydrogen chloride and of a stream a2 comprising oxygen into an oxidation zone and catalytic oxidation of hydrogen chloride to chlorine, giving a product gas stream a3 comprising chlorine, water, oxygen, carbon dioxide and inert gases; b) cooling of the product gas stream a3 and removal of water and hydrogen chloride as aqueous hydrochloric acid, leaving a gas stream b comprising chlorine, water, oxygen, carbon dioxide and inert gases; c) optional drying of the gas stream b) to leave a gas stream c which is substantially free of water and comprises chlorine, oxygen, carbon dioxide and inert gases; d) at least partial liquefaction of the gas stream c and of a chlorine-rich recycle stream f1 comprising chlorine, oxygen and carbon dioxide by compression and cooling, giving an at least partially liquefied stream d; e) gas/liquid separation of the stream d into a gas stream e1 comprising chlorine, oxygen, carbon dioxide and inert gases and into a liquid stream e2 comprising chlorine, oxygen and carbon dioxide; f) feeding of at least part of the gas stream e1 into a membrane separation unit and fractionation by membrane separation to give the chlorine-rich recycle stream f1 and a gas stream f2 which is low in chlorine and comprises chlorine, oxygen and carbon dioxide and recirculation of the chlorine-rich recycle stream f1 to step d); g) separation of the liquid stream e2 by distillation into a chlorine stream g1 and a stream g2 comprising essentially oxygen and carbon dioxide.
