Patent number: 10173195Abstract: Processes relating to thermal activation (or cracking) of ethane to an intermediate, low purity raw ethylene stream in a first stage. This stream is then mixed with a stream of biomass-derived ethanol that may contain four volume percent or more of water. The resulting mixture is reacted over a suitable catalyst at temperatures and pressures suitable to produce gasoline-range and diesel-range blend stock.Type: GrantFiled: December 16, 2014Date of Patent: January 8, 2019Assignee: Phillips 66 CompanyInventors: Jianhua Yao, Dhananjay Ghonasgi, Tushar Choudhary, Warren Ewert

Patent number: 10087380Abstract: A process for converting ethane to liquid fuels may involve directing an ethane stream into an ethane cracking unit to produce an intermediate hydrocarbon stream and a raw ethylene stream; fractionating the intermediate hydrocarbon stream into a gasoline fraction and a diesel fraction; introducing the raw ethylene stream into an oligomerization unit; contacting the raw ethylene stream with an oligomerization catalyst to produce a liquid hydrocarbon stream and an off-gas stream; recycling an off-gas recycle stream from an off-gas stream of the oligomerization unit separation unit to an inlet of the oligomerization reactor; introducing at least part of the off-gas stream into a hydrogenation reactor to remove unconverted olefins; separating a hydrogen component and a plurality of light paraffin components in a post hydrogenation reactor separation unit using a PSA technology or membrane technology; and recycling the light paraffins stream into the ethane cracking unit.Type: GrantFiled: December 16, 2014Date of Patent: October 2, 2018Assignee: Phillips 66 CompanyInventors: Jianhu Yao, Dhananjay Ghonasgi, Tushar Choudhary, Warren Ewert

Patent number: 9731270Abstract: Converting ethane may include directing a gaseous stream from a gas well into a fractionator for fractionating and producing a post-fractionator ethane stream, which is directed into a thermal activation unit for heating and raising the temperature of the post-fractionator ethane stream thereby creating an activated ethane stream, which is directed into a quench tower thereby creating a quenched stream, which may be converted in a catalytic conversion unit to a mixed product stream containing hydrogen and C1-C15 hydrocarbons; directing the mixed product stream into a first separation unit forming a stream of C4+ hydrocarbon product and a stream of C1-C3 hydrocarbons; directing the stream of C1-C3 hydrocarbons into a catalytic hydrogenation reactor thereby imparting hydrogen into a post-hydrogenation reactor stream, which is directed directly into a second separation unit thereby creating a light hydrocarbons recycle stream, which may be recycled into the thermal activation unit, and a hydrogen and methane strType: GrantFiled: December 16, 2014Date of Patent: August 15, 2017Assignee: PHILLIPS 66 COMPANYInventors: Jianhua Yao, Dhananjay Ghonasgi, Tushar Choudhary, Warren Ewert

Patent number: 9545613Abstract: Systems relating to thermal activation (or cracking) of ethane to an intermediate, low purity raw ethylene stream in a first stage. The system then mixes this stream with a stream of raw biomass-derived ethanol that may contain more than four volume percent of water. The resulting mixture is reacted over a suitable catalyst at temperatures and pressures suitable to produce gasoline-range and diesel-range blend stock.Type: GrantFiled: December 16, 2014Date of Patent: January 17, 2017Assignee: Phillips 66 CompanyInventors: Jianhua Yao, Dhananjay Ghonasgi, Tushar Choudhary, Warren Ewert

Publication number: 20060151358Abstract: A desulfurization system is operated in a manner which optimizes sulfur removal and octane retention. When the desulfurization reactor is operated at a specific ratio of total pressure to hydrogen partial pressure (PT/PH) and/or within a specific temperature range, optimum sulfur removal and octane retention are realized. The desulfurization reactor can be maintained at these optimized operating conditions by automatically adjusting one or more operating parameters of the desulfurization reactor in order to maintain a substantially constant hydrogen partial pressure (PH) in the reactor. Maintaining a relatively constant hydrogen partial pressure (PH) in the desulfurization reactor helps ensure a relatively consistent degree of desulfurization.Type: ApplicationFiled: January 13, 2005Publication date: July 13, 2006Inventors: Ronald Brown, Warren Ewert
