ABSTRACT:
Process for separating H.sub.2 S from CO.sub.2, both contained in a treated gas, wherein said gas is contacted with a solution which selectively absorbs H.sub.2 S, wherefrom H.sub.2 S is separated in a regeneration zone, CO.sub.2 being released, said contact step being effected in a contact apparatus comprising 1 to 10 stages each formed of parallel vertical tubes whose bottom portion is provided with injection means of the cyclonic type imparting to the supplied gas and liquid a swirling ascending motion.
