The decarbonation and desulfurization of a combustion smoke 1 is carried out by contacting combustion smoke in unit A with an aqueous solution comprising N, N, N ', N'-Tetramethylhexane-1,6 -diamine. The absorbent solution 3 loaded with acidic compounds is regenerated in a regeneration zone R so as to release CO2 in gaseous form, then submitting at least a portion of the regenerated absorbent solution to an extraction operation of the sulfur oxides in the reaction zone. unit P to obtain an absorbent solution depleted in sulfur oxide. |
