Abstract

Le procédé propose de capturer des composés acides, tels le CO et l'H S, contenus dans un gaz, par exemple des fumées de combustion ou un gaz naturel, en effectuant les étapes suivantes : a) on met en contact le gaz à traiter avec une solution absorbante comportant des amines en solution aqueuse de manière à obtenir un gaz appauvri en composés acides et comportant des traces d'amines et une solution absorbante enrichie en composés acides, b) on régénère au moins une partie de la solution absorbante enrichie en composés acides dans une colonne de régénération de manière à obtenir une solution absorbante régénérée et un effluent gazeux riche en composés acides, la solution absorbante régénérée étant recyclée à l'étape a) en tant que solution absorbante, c) on condense par refroidissement une partie dudit effluent gazeux pour obtenir des condensats liquides et un gaz enrichi en composés acides, puis on introduit au moins une partie des condensats dans la colonne de régénération; d) on met en contact dans une section de lavage le gaz appauvri en composés acides obtenu à l'étape a) avec un flux d'eau liquide de manière à obtenir un gaz appauvri en amine et une eau enrichie en amine, e) on recycle dans le procédé une partie de l'eau enrichie en composés absorbants obtenue en fond de la section de lavage.
