摘要
SuperSulf process refers to an innovative reactor design consisting of internal cooling and heating thermoplate exchangers where it is filled by the Claus type catalysts between plates in the SRU and hydrogenation catalysts in the tail gas unit. SuperSulf reactor consists of 3 reactor zones in the sulfur recovery which operates as a SubDewPoint process where the mode of operation are controlled by switching valves on the utilities streams high pressure steam and high quality water and steam where the first 2 zones operate as hot and cold and switches to cold and hot where the produced sulfur is condensed. The third zone operates as cold all the time where consists of the last sulfur condenser by producing Low pressure steam. The tail gas unit consists of 2 reactor zones of hydrogenation reactor and hydrolysis reactor with internal plate cooling then followed by the tail gas amine with a selective solvent. The thermal incineration system can meet less than 50 ppmv of SO2 and with caustic incineration less than 10 ppmv of SO2 resulting zero emission.
