Abstract

A process for producing purified gas from a sour gas comprising H2S, the process comprising the steps of : (a) contacting a sour gas comprising H2S with an absorbing liquid for H2S to transfer H2S from the sour gas to the absorbing liquid, thereby producing an H2S- rich absorbing liquid and the purified gas; (b) transferring H2S from the H2S-rich absorbing liquid to a stripping gas, thereby obtaining a feed acid gas stream enriched in H2S; (c) providing the feed acid gas stream enriched in H2S and a gas stream comprising SO2 to a sulphur recovery system comprising two or more Claus catalytic stages in series, each Claus catalytic stage comprising a Claus catalytic reactor coupled to a sulphur condenser, wherein either the feed acid gas stream enriched in H2S or the gas stream comprising SO2 is completely routed to the first Claus catalytic stage while the other stream is split into two or more substreams and each of the two or more substreams are supplied to a different Claus catalytic stage, wherein the amount of feed acid gas stream enriched in H2S or the amount of gas stream comprising SO2 is supplied to the Claus catalytic stages in dependence of the temperature in the Claus catalytic reactors to enable that the temperature in the Claus catalytic reactors is moderated; (d) reacting at least part of the H2S in the feed acid gas stream enriched in H2S with SO2 to elemental sulphur in the two or more Claus catalytic reactors.
