Patent number: 11760632Abstract: Embodiments of the disclosure provide a method and system for sulfur recovery. A Claus tail gas stream is fed to a hydrogenation reactor to produce a hydrogenated gas stream. The hydrogenated gas stream is fed to a quench tower to produce a quenched gas stream. The quenched gas stream is fed to a first stage adsorption vessel of first stage adsorption unit to produce a first outlet gas stream. The first outlet gas stream is fed to a second stage adsorption vessel of a second stage adsorption unit to produce a second byproduct gas stream. The first stage adsorption vessel is regenerated to produce a first byproduct gas stream. The second stage adsorption vessel is regenerated to produce a second outlet gas stream including hydrogen sulfide. Optionally, a portion of the second byproduct gas stream or nitrogen can be fed to the first stage adsorption vessel or the second stage adsorption vessel for regeneration. Optionally, a sales gas can be fed to the second stage adsorption vessel for regeneration.Type: GrantFiled: December 28, 2019Date of Patent: September 19, 2023Assignee: Saudi Arabian Oil CompanyInventors: Georgios Lithoxoos, Yuguo Wang, Rashid M.

Patent number: 4623448Abstract: A method and an apparatus are provided for removing halogenated polyphenyl materials from used or waste oil supplies. Waste or used lube stock is subjected to rerefining procedures in order to remove many of the impurities found in such waste or used stocks. The rerefined stock which is contaminated with halogenated polyphenyls is continuously pumped under pressure and mixed with highly pressurized hydrogen gas which is heated to a relatively low temperature and passed through a bed of catalyst in order to promote a reaction that forms a hydrogen halide and a polynuclear aromatic material that does not exhibit the environmental and health hazards of a halogenated polyphenyl material such as PCB's.Type: GrantFiled: March 12, 1985Date of Patent: November 18, 1986Assignee: Moreco Energy, Inc.Inventors: John P.
