A method for removing sulfur-containing compounds is provided. In one embodiment, the method includes selectively separating a feed stream (118) comprising carbon dioxide and one or more sulfur-containing compounds, including hydrogen sulfide, at conditions sufficient to produce a first stream (122) comprising carbon dioxide and hydrogen sulfide and a second stream (124) comprising carbon dioxide and hydrogen sulfide. A molar ratio of carbon dioxide to hydrogen sulfide in the first stream is greater than a molar ratio of carbon dioxide to hydrogen sulfide in the second stream, and a molar ratio of hydrogen sulfide in the first stream to hydrogen sulfide in the second stream is about 0.005 or more.
L~invention porte sur un procédé d~enlèvement de composés contenant du soufre. Selon un mode de réalisation, le procédé consiste à séparer de manière sélective un courant d~alimentation (118) comprenant du dioxyde de carbone et un ou plusieurs composés contenant du soufre, englobant du sulfure d~hydrogène, dans des conditions suffisantes pour produire un premier courant (122) comprenant du dioxyde de carbone et du sulfure d~hydrogène et un second courant (124) comprenant du dioxyde de carbone et du sulfure d~hydrogène. Le rapport molaire du dioxyde de carbone au sulfure d~hydrogène dans le premier courant est supérieur au rapport molaire du dioxyde de carbone au sulfure d~hydrogène dans le second courant, et le rapport molaire du sulfure d~hydrogène dans le premier courant au sulfure d~hydrogène dans le second courant est supérieur ou égal à environ 0,005.
