Patent number: 11708267Abstract: A process and apparatus for managing hydrogen sulfide in a refinery is provided. In the process, a hydrogen sulfide stream from said refinery is fed to a sulfur recovery unit to produce sulfur and a sulfur compound stream or to a thermal oxidizer. The sulfur compound stream and the hydrogen sulfide stream are then thermally oxidized to produce a sulfur oxide stream. The sulfur oxide stream is then reacted with an ammonia stream. In aspect, the product of the reaction can be a fertilizer. The ammonia stream can be obtained from stripping the hydrogen sulfide stream.Type: GrantFiled: December 10, 2021Date of Patent: July 25, 2023Assignee: UOP LLCInventors: Jan De Ren, Haiyan Wang, Joao Jorge Da Silva Ferreira Alves, Ian Clarke, William J.

Patent number: 10458329Abstract: A power generation process for use in a processing unit that includes the steps of: using a regenerator to produce a flue gas stream; removing catalyst particles from the flue gas stream; routing the flue gas stream to a combustor/expander unit after performing the step of removing catalyst particles; and using rotation of the turbine of the combustor/expander unit as a source of rotary power. Preferably, the combustor/expander unit includes a combustion chamber and a power recovery turbine housed within a single casing. In certain embodiments, the flue gas stream is routed between the regenerator and the combustor/expander without passing through a compressor.Type: GrantFiled: March 6, 2014Date of Patent: October 29, 2019Assignee: UOP LLCInventors: Xin X.

Patent number: 8937206Abstract: The process converts FCC olefins to heavier compounds. The heavier compounds are more easily separated from the unconverted paraffins. The heavier compounds can be recycled to an FCC unit or delivered to a separate FCC unit. Suitable conversion zones are oligomerization and aromatic alkylation zones.Type: GrantFiled: March 27, 2014Date of Patent: January 20, 2015Assignee: UOP LLCInventors: Joao Jorge da Silva Ferreira Alves, James E.

Publication number: 20130317267Abstract: Embodiments of methods for the production of linear alkylbenzene and optionally biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C9 to C14 range and a second stream of isoparaffins. The first stream is dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product. Optionally a second portion of the paraffins and the isoparaffins are processed to form biofuel.Type: ApplicationFiled: July 30, 2013Publication date: November 28, 2013Applicant: UOP LLCInventors: Amarendra Anumakonda, Srikantiah Raghuram, Joao Jorge da SIlva Ferreira Alves, Andrea G.

Publication number: 20130131417Abstract: One example method of the invention includes a process for producing an olefin comprising the steps of communicating a feed stream that comprises a paraffin to a distillation section, communicating a distillation section output stream to a reactor and reacting the distillation section output stream in the reactor to produce a reactor output stream comprising an olefin. A splitter feed stream that is in communication with and downstream from the reactor output stream is communicated to an olefin splitter, and a splitter output stream is communicated to a heat pump compressor. A heat pump compressor output stream is communicated to the distillation section and heat is used from the heat pump compressor output stream to reheat a distillation section stream that contains unreacted paraffin.Type: ApplicationFiled: November 18, 2011Publication date: May 23, 2013Applicant: UOP LLCInventors: Greg Werba, Steven Lankton, Steven Kozup, Joao Jorge da Silva Ferreira Alves, Charles P.

Patent number: 8414763Abstract: A process is disclosed for recovering product from catalytically converted product streams. Gaseous unstabilized naphtha from an overhead receiver from a main fractionation column is compressed in a compressor. Liquid unstabilized naphtha from the overhead receiver and liquid naphtha fraction from the compressor are sent to a naphtha splitter column upstream of a primary absorber. Consequently, less naphtha is circulated in the gas recovery system.Type: GrantFiled: November 9, 2009Date of Patent: April 9, 2013Assignee: UOP LLCInventors: Joao Jorge da Silva Ferreira Alves, Saadet Ulas Acikgoz, Xin X.

Patent number: 8388830Abstract: A process is presented for the removal of oxygen from a hydrocarbon stream. The oxygen can react and cause polymerization of the hydrocarbons when the hydrocarbon stream is heated. Controlling the removal of the oxygen from the hydrocarbon stream produces a hydrocarbon stream that is substantially free of oxygen and has a reduced activity for generating undesired compounds.Type: GrantFiled: June 7, 2011Date of Patent: March 5, 2013Assignee: UOP LLCInventors: Stephen W.
