A process is described for the recovery of hydrogen chloride in anhydrous form (42) from a dry mixture of one or more non-condensable gases, hydrogen chloride and heavier components which may be present (16), which process comprises using a halogenated hydrocarbon solvent (22), and especially a chlorinated hydrocarbon solvent, to preferentially absorb hydrogen chloride and heavier materials from the dry mixture, with the non-condensable gases contained in the mixture being carried through as a gas stream (38) and the rich solvent stream (36) being processed to separate out and recover the hydrogen chloride therein in anhydrous form.
