摘要： 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 comprisinga) from 0.1 to 50% by weight of one or more mono-cyclic or bicyclic nitrogen heterocycles which are unsubstituted and/or monosubstituted or poly-substituted 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 component D,e) from 0 to 35% by weight of K2CO3 as component E,where the sum of components A, B, C, D and E is 100% by weight.

摘要： The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate. Process for removing acidic components, e.g. carbon dioxide, hydrogen sulfide, COS, carbon disulfide and mercaptans from gases comprises contacting the crude gas with an adsorbent obtaining a pure gas deficient in acidic gas components and an absorbent charged with acidic gas components. The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate.
