Abstract
The invention relates to a process and apparatus for recovering sulfur (). In a sour gas scrubbing apparatus (S) comprises a scrubbing part (SP) and a regeneration part (RP), wherein sulfur components and carbon dioxide are selectively removed from a crude synthesis gas () with the aid of a circulating scrubbing agent (). A sulfur-containing gas fraction () produced during the regeneration of loaded scrubbing agent is supplied to a sulfur recovery system (SR) in which an off-gas () comprising carbon dioxide and also sulfur components is formed. The off-gas is hydrogenated (H) and subsequently subjected to a gas scrubbing operation (Z). The hydrogenated off-gas () is scrubbed, independently of the crude synthesis gas (), and scrubbing agent () removed from the scrubbing agent circuit of the sour gas scrubbing apparatus (S) is used to scrub out sulfur components from the hydrogenated off-gas ().
