ABSTRACT:
Processes comprising: providing a crude gas stream having a temperature not exceeding 40° C., the crude gas stream comprising hydrogen chloride and at least one organic impurity; condensing at least a portion of the at least one organic impurity from the crude gas stream at a temperature not exceeding 0° C. to form a prepurified gas stream and a condensate comprising condensed organic impurity; subjecting at least a portion of the prepurified gas stream to adsorption on an adsorption medium to provide a purified gas stream; and separating the condensate into at least a head gas stream comprising residual hydrogen chloride and a sump stream comprising at least a portion of the condensed organic impurity.
