Process for purifying a gas containing hydrogen sulfide and carbon dioxide and apparatus therefor

Process for separating H2S from CO2, both contained in a treated gas, wherein said gas is contacted with a solution which selectively absorbs H2S, wherefrom H2S is separated in a regeneration zone, CO2 being released, said contact step being effected in a contact apparatus comprising 1 to 10 stages...
