A selective absorbing and regeneratable liquid capable of absorbing H.sub.2 S is introduced at the upper portion of the column and flows successively into the zones (11) and (17) and finally into (12). The absorbing liquid meets the gas to be treated, which is injected through a conduit (9), in the zone (11) while the regenerated absorbing liquid is tapped at the bottom (4) of the column and brought back through a conduit (5) into said zone (11). At the head (2) of the column, a gas having a reduced content of H.sub.2 S is discharged and by means of a system (18) provided in the zone (17) an acid gas fraction rich in H.sub.2 S is tapped. Application to the production of a highly H.sub.2 S enriched gas effluent from a gas containing H.sub.2 S and an appreciable quantity of CO.sub.2.

    摘要: Method and devices for the selective removal of H.sub.2 S from an H.sub.2 S-containing gas by contacting the gas in an absorption column with an H.sub.2 S-selective absorbent liquid and transferring the H.sub.2 S-charged absorbent liquid to the upper part of a second column. The charged absorbent liquid then travels to a regeneration zone at the bottom of the column, where it is heated to a temperature at which the absorbent liquid is vaporized and the H.sub.2 S is released.The regeneration zone temperature causes the absorbent liquid vapor to strip the H.sub.2 S back to the upper part of the column where it forms an equilibrium with the H.sub.2 S-charged absorbent liquid at a temperature not more than 30.degree. C. higher than the injection temperature of the absorbent liquid in the absorption column, which equilibrium temperature is maintained by the temperature in the regeneration zone. The H.sub.2 S-enriched vapor formed at the equilibrium point is then tapped.
