Patent number: 11959029Abstract: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.Type: GrantFiled: December 19, 2022Date of Patent: April 16, 2024Assignee: UOP LLCInventors: Stanley S. Carp, David Banks, Alan K. Bedell, Gregory Funk, Keith Allen Couch, Stanley Joseph Frey, Cora Wang Ploentham

Patent number: 11708537Abstract: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked to produce light olefins. A pyrolysis gas stream is separated into a light pyrolysis gas stream and a heavy pyrolysis gas stream. A light pyrolysis gas stream is separated into a normal paraffins stream and a non-normal paraffins stream. A normal paraffins stream is thermally cracked.

Patent number: 11667848Abstract: A process for reducing pressure of a vapor stream used for reducing a temperature or pressure in a reactor. A pressure of a vapor stream is reduced with a turbine to provide a lower pressure vapor stream. The vapor stream rotates a turbine wheel within the turbine. The turbine wheel is configured to transmit rotational movement to an electrical generator. Thus, electricity is generated with the turbine. The lower pressure vapor stream is injected into a reactor and reduces a temperature in the reactor or reduces a partial pressure of a hydrocarbon vapor in the reactor.Type: GrantFiled: September 30, 2020Date of Patent: June 6, 2023Assignee: UOP LLCInventors: Stanley Joseph Frey, Keith Allen Couch, Donald A. Eizenga, James W. Harris

Patent number: 11427771Abstract: A slurry separator comprising a moving blade that wipes slurry oil onto a wall of the slurry separator for separating a recovered oil stream from a concentrated residue stream has the capability of maximizing recovery of the LCO from slurry oil as well as removing both the catalyst fines as well as coke particles suspended in the slurry oil. The slurry separator can be fed directly from the main column bottoms. Advantageously, the process and apparatus can enable the FCC unit to achieve higher production of LCO and higher value clarified slurry oil more efficiently.Type: GrantFiled: March 23, 2020Date of Patent: August 30, 2022Assignee: UOP LLCInventors: Keith Allen Couch, Joseph Mark Houdek
