Abstract

A process for the removal of acid gases (H2S, CO2 and COS) from a gas mixture by contacting the gas mixture with an aqueous solution comprising: (a) a physical solvent for acid gases, e.g. sulfolane; (b) a tertiary amine (e.g., methyl- diethanolamine or diethyl-monoethanolamine); (c) a secondary and/or primary amine with a <IMAGE> which is not lower than the <IMAGE> of the tertiary amine minus one (e.g., di-isopropanolamine), in an amount of 1 to 50 mol.% calculated on the said primary, secondary and tertiary amines together.
