Patent number: 10279329Abstract: Methods and apparatus to produce alkynes are described. The method includes combusting fuel and an oxidizer in a combustion zone to create a carrier gas stream, which is accelerated to supersonic speed in an expansion zone. A feedstock material is injected into a feedstock injection zone using two or more pluralities of injection nozzles. The injection nozzles are arranged annularly. The carrier gas stream is transitioned from supersonic speed to subsonic speed to create a shockwave in a reaction zone. The reaction zone is directly connected to the feedstock injection zone, and the shockwave is created adjacent to the feedstock injection zone. The carrier gas stream and the feedstock material are simultaneously mixed and reacted.Type: GrantFiled: October 18, 2017Date of Patent: May 7, 2019Assignee: UOP LLCInventors: Rajeswar R. Gattupalli, Vinayender Kuchana, Laura E. Leonard, Vighneswara R. Kollati, Aziz Sattar, Mohamad R. Mostofi-Ashtiani, Peter Shafe

Patent number: 9458068Abstract: One exemplary embodiment can be a process for removing one or more sulfur compounds from a first liquid. The process can include passing the first liquid through a first inlet and a second liquid through a second inlet of a vessel, passing the first and second liquids through the passageway for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid, and passing the first liquid through the first outlet and the second liquid through the second outlet. Often, the vessel has a plurality of vortex contactors, and a first outlet and a second outlet. The plurality of vortex contactors can include a first vortex contactor, in turn having at least one wall forming a perimeter about an interior region and including a first side and a second side forming a passageway communicating the first liquid from an exterior to the interior region, and a frustum positioned proximate to the passageway and abutting the at least one wall.Type: GrantFiled: December 10, 2012Date of Patent: October 4, 2016Assignees: UOP LLC, BORESKOV INSTITUTE OF CATALYSISInventors: Andrey Kuzmin, Aziz Sattar, Lev Davydov, Jonathan Andrew Tertel

Publication number: 20150361010Abstract: A process and apparatus for the pyrolysis of methane into acetylene. A heat exchanger is disposed downstream of a supersonic reactor and is used to recover heat from the quenched effluent. Effluent may flow on a shell side of the heat exchanger and cooling fluid may flow on a tube side. Additionally, a separator is disposed downstream of the heat exchanger so that the effluent is capable of freely draining into the separator. The heat exchanger, separator, or both may be disposed at an angle between 20° to 90° from the horizon so that the fluid is capable of freely draining into the separator. The separator includes an outlet gas valve that may be used to control the pressure within the reactor.Type: ApplicationFiled: June 11, 2014Publication date: December 17, 2015Inventors: Laura E.
