Method for eliminating the acid compounds contained in a gaseous effluent, comprising bringing into contact, in the absorption column C1, an effluent gas (1) with an absorbent solution (4) comprising water and at least one nitrogen compound of the following general formula: (I), in which x is equal to 0 or 1, and in which R is chosen from a hydrogen atom or a radical -(CH2)3-N-(CH3)2 when x is equal to 1, said absorbent solution not comprising Ν,Ν,Ν',Ν'-tetramethyl-l,6-hexanediamine. The nitrogen compound is, for example, bis-(3-dimethylaminopropoxy) -1,2-ethane having the following formula: (II) |
