    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: A catalyst for the desulfurization and deodorization of gasoline, which is expressed by the formula: QlBmHn[AxMyOz](1+m+n)−, where: Q denotes a quaternary ammonium cation consisting of R1R2R3R4N+, in which R1, R2, R3, and R4 each denotes independently a C1 to C20 saturated alkyl group, respectively, provided that at least one of R1, R2, R3, and R4 denotes a C4 to C20 saturated alkyl group; B denotes a metal cation of Na+ or/and K+; H denotes a hydrogen atom; A denotes a central atom of B, P, As, Si or Al; M denotes a coordinated atom of W or Mo; O denotes an oxygen atom; 1≦l≦10, 0≦m≦3, 0≦n≦3, l+m+n≦14, x=1 or 2, 9≦y≦18, 34≦z≦62, and l, m, n, y and z all are integers. A method of the desulfurization and deodorization of gasoline by using the catalyst comprises the steps of: mixing the catalyst and an aqueous solution of hydrogen peroxide, and then adding the gasoline to react them with stirring under conditions of 25 to 90° C. and 0.1 to 1 MPa for 10 to 180 min. An odorless gasoline can be obtained through settlement or centrifugation, and the catalyst is recovered.
