Abstract
The present invention relates to a method of removing acid gases, notably carbonyl sulfide, contained in gaseous effluents, comprising: an acid gas absorption stage by contacting the gaseous effluent with an aqueous solution comprising 2-[2-amino-1-(aminomethyl)ethoxy]ethanol, and possibly another alkanolamine and an organic compound, and at least one aqueous solution regeneration stage. The method can comprise a second aqueous solution regeneration stage. The regeneration stages are carried out by expansion and/or thermal regeneration.
