Abstract

L'invention concerne un procédé d'élimination de co2 d'un courant gazeux, qui comprend les étapes suivantes : (a) la mise en contact dans une étape d'absorption de co2 d'un courant gazeux comprenant du co2 avec un premier liquide d'absorption comprenant de l'ammoniac; (b) le passage du liquide d'absorption utilisé résultant de l'étape (a) dans une régénération; (c) la régénération du premier liquide d'absorption par libération du co2 du liquide d'absorption utilisé et le recyclage du premier liquide d'absorption dans l'étape (a); (d) l'introduction du co2 libéré à l'étape (c) dans un second liquide d'absorption; (e) la mise en contact dans une étape d'absorption de contaminants du courant gazeux quittant l'étape (a) avec le second liquide d'absorption; et (f) l'extraction d'une partie du liquide d'absorption utilisé résultant de l'étape (e) et le passage de ladite partie de liquide dans la régénération de l'étape (c), avant le recyclage du liquide d'absorption utilisé résultant de l'étape (e) en tant que second liquide d'absorption dans l'étape (d).
