Patent number: 11376548Abstract: Process of treating a net gas stream is disclosed. The process includes sending the net gas stream to a compressor to produce a compressed gas stream. The compressed gas stream is then sent to a pressure swing adsorption unit to produce a hydrogen product stream and a tail gas stream. Tail gas stream from the pressure swing adsorption unit is sent to a first membrane unit to produce a first permeate stream and a first non-permeate stream. Portion of the tail gas stream is sent to a second membrane unit to produce a second permeate stream and a second non-permeate stream.Type: GrantFiled: September 4, 2019Date of Patent: July 5, 2022Assignee: UOP LLCInventors: Bradley P.

Publication number: 20220112430Abstract: The process produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The recycle gas is recycled to the hydrotreating reactor without removing hydrogen sulfide, which is needed in the biorenewable feed to keep the hydrotreating catalyst active. A purification unit can be utilized on a purge gas stream to purify the gas and improve hydrogen concentration in the recycle gas when added to the recycle gas.Type: ApplicationFiled: September 2, 2021Publication date: April 14, 2022Inventors: David A.

Patent number: 11040926Abstract: An integrated process for maximizing recovery of aromatics is provided. The process comprises passing at least a portion of a xylene column bottoms stream to a heavy aromatics column to provide a heavy aromatics column bottoms stream comprising C9+ aromatics and a heavy aromatics column overhead stream. The heavy aromatics column bottoms stream is passed to a second stage hydrocracking reactor of a two-stage hydrocracking reactor. In the second stage hydrocracking reactor, the heavy aromatics column bottoms stream is hydrocracked in the presence of a hydrocracking catalyst and hydrogen to provide a hydrocracked effluent stream.Type: GrantFiled: July 22, 2019Date of Patent: June 22, 2021Assignee: UOP LLCInventors: Gautam Pandey, Krishna Mani, Deepak Bisht, Priyesh Jayendrakumar Jani, Vikrant Vilasrao Dalal, Ram Ganesh Rokkam

Patent number: 10851315Abstract: Processes for the production of a gasoline blend. A C7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C7 saturated hydrocarbons are convert to C7 olefins. The C7 olefins have a higher octane number than the C7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C7 olefins can be blended in a gasoline pool. C5 and C6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C7 components.Type: GrantFiled: June 27, 2019Date of Patent: December 1, 2020Assignee: UOP LLCInventors: Mark P.
