Abstract

La présente invention concerne un procédé pour élever le rapport H2 S/CO2 dans un mélange de gaz de manière à préparer un mélange de gaz ayant un rapport H2 S/CO2 désiré. CO2 et du H2 S du mélange de départ sont absorbés dans une solution aqueuse d'une amine (l'absorbant 2). Le gaz absorbé est libère par l'absorbant chargé dans une colonne de régénération 5. Le H2 S d'une portion du gaz libéré est absorbé sélectivement dans l'absorbant 13 et l'absorbant chargé ainsi obtenu est conduit à la colonne de régénération. La portion ci-dessus est choisie de manière que le gaz libéré provenant de la colonne de régénération air le rapport H2 S/CO2 désiré. Application au procédé Claus.The present invention relates to a process for raising the H2 S / CO2 ratio in a gas mixture so as to prepare a gas mixture having a desired H2 S / CO2 ratio. CO2 and H2 S from the starting mixture are absorbed in an aqueous solution of an amine (absorbent 2). The absorbed gas is released by the absorbent loaded into a regeneration column 5. The H2 S of a portion of the released gas is selectively absorbed in the absorbent 13 and the loaded absorbent thus obtained is led to the regeneration column. The above portion is chosen so that the gas released from the regeneration column airs the desired H2 S / CO2 ratio. Application to the Claus process.
