Zusammenfassung:Acid gases, particularly carbon dioxide, are removed from gas mixtures by washing with an aqueous solution of a polyamine having at least four amino-groups or of a polyamine mixture including at least one such polyamine. Examples of such polyamines are NN'-bis-(3-aminopropyl)- ethylenediamine, tripropylenetetramine and tetrapropylenepentamine.
