Abstract
Official abstract text for this publication.
The invention relates to a process and apparatus for recovering sulfur ( 9 ). 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 ( 2 ) with the aid of a circulating scrubbing agent ( 3 ). A sulfur-containing gas fraction ( 8 ) produced during the regeneration of loaded scrubbing agent is supplied to a sulfur recovery system (SR) in which an off-gas ( 10 ) 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 ( 12 ) is scrubbed, independently of the crude synthesis gas ( 2 ), and scrubbing agent ( 13 ) 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 ( 12 ).
