摘要： SuperDegas process refers to innovative process of the liquid sulfur collection and degassing which takes place in the underground container in a concrete pit or a carbon steel vessel located in the concrete pit. SuperDegas process consists of at least three compartments: (1) sulfur collection to agitate and create turbulent, higher velocity, and higher pressure in the liquid sulfur for more effective degassing by using vertical pumps; (2) consists of the proprietary air spargers and Morpholine catalyst for degassing. Morpholine catalyst degas the liquid sulfur 30 times faster than Quinoline or any other solvent with sparging air and within 1 hour residence time from 16-30 hours and to meet less than 10 ppmw of H2S in liquid sulfur. (3) The last compartment receives the degassed sulfur by overflow and transport through a pump or pumps to other facilities. An eductor will sweep vapor phase containing H2S, vaporized Morpholine with air where the pit vent can be sent to incineration or the reaction furnace. The tail gas stream from SRU can sweep the pit and the discharge shall be recycled to the tail gas unit, which ultimately zero emission can be achieved.

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.
