The method involves regenerating an absorbing solution loaded with acid compounds in a regeneration column (C2) to liberate the acid compounds under gaseous form and to obtain a regenerated absorbing solution. A portion of the regenerated solution is separated into a fraction enriched in water and a fraction enriched in reactive compound i.e. N,N,N',N'-Tetramthylhexane-l, 6-diamine (TMHDA). A part of the fraction enriched in water is vaporized for producing a vapor or the fraction enriched in water or fraction enriched in reactive compound is purified. The reactive compound is selected from a group constituted by amines, alcanolamines, polyamines, amino acids, alkaline amino acid salt, amides, urea, phosphates, carbonates and borates of alkali metals. |
