摘要

To form (15) Hydrolysis gases contact hydrolysis (57) [Abstract] waste gas (6) in (1), contains SO ₂ and (i) H ₂ S, not containing COS and CS ₂ . Introducing one of (2a, 2b) of the Claus Sekkai two zones (17) after being placed in parallel to (2a) and the cooling gas is hydrolyzed. Sekkai other zones (2b) is subjected to cooling then playback. Play in open circuit, carried gas stream gas extraction (17) from front (15) cooled by (19, 36), between (17) and cooling (19) extraction regeneration effluent gas (24b) and re-injected into the (15) Gas (29 and 20). In an open circuit, carried gas stream withdrawn from (6) by the waste gas (11, 36) cooling reactor (2b), between (8) and heating (11) extraction cooled effluent gas (24b) to be re-introduced into the (6) waste gas (29,13).
