A PROCESS FOR REMOVING ACIDIC GAS CONSTITUENTS, OF THE GROUP CONSISTING OF CO2, H2S, COS, CS2 AND MERCAPTANS, FROM GASES, IN WHICH, IN AN ABSORPTION STEP, A DIRTY GAS RICH IN ACIDIC GAS CONSTITUENTS IS BROUGHT INTO CONTACT WITH AN ABSORPTION MEDIUM, AS A RESULT OF WHICH A CLEAN GAS LOW IN ACIDIC GAS CONSTITUENTS AND AN ABSORPTION MEDIUM LADEN WITH ACIDIC GAS CONSTITUENTS ARE OBTAINED, THE ABSORPTION MEDIUM USED BEING A MIXTURE COMPRISING A) FROM 0.1 TO 50% BY WEIGHT OF ONE OR MORE MONO-CYCLIC OR BICYCLIC NITROGEN HETEROCYCLES WHICH ARE UNSUBSTITUTED AND/OR MONOSUBSTITUTED OR POLYSUBSTITUTED ON THE CARBON BY OH, C1-C3 ALKYL AND/OR C1-C3 HYDROXYALKYL AND WHICH HAVE FROM 5 TO 14 RING ATOMS AND 1 OR 2 HETEROCYCLICALLY BOUND NITROGEN ATOMS PER RING AS COMPONENT A,B) FROM 1 TO 60% BY WEIGHT OF A MONOHYDRIC AND/OR POLYHYDRIC ALCOHOL AS COMPONENT B,C) FROM 0 TO 60% BY WEIGHT OF AN ALIPHATIC AMINOALCOHOL AS COMPONENT C,D) FROM 0 TO 98.9% BY WEIGHT OF WATER AS COMPONET D,E) FROM 0 TO 35% BY WEIGHT OF K2CO3 AS COMPONENT E,WHERE THE SUM COMPONENTS A,B,C,D AND E IS 100% BY WEIGHT.FIG 1
