<p>A process for the removal of acidic gages from a gaseous mixture containing the game by contacting the said gaseous mixture countercurrently in a contacting zone at a temperature in the range of 15 to 135.degree.C and at a pressure of from 1 to 100 kg/cm2 abs., with an aqueous absorbent comprising an amine with a pkb of 3-14 at 25.degree.C in an amount of 10 to 70% by weight and sulfolane and/or its derivatives in an amount of 25 to 70% by weight, which aqueous absorbent is introduced at the top of the contacting zone, and a fat aqueous absorbent is finally withdrawn from the contacting zone at the bottom thereof for regeneration by means of heating and/or stripping, in which process at an intermediate point at the lower part of the said contacting zone the said aqueous absorbent is withdrawn from said contacting zone as a semi-fat absorbent and is reintroduced into the said lower part of said contacting zone after having been cooled externally, for further contacting with the said aqueous mixture.</p> |
