Patent number: 11939289Abstract: The selective dimerization of isoolefins, such as isobutene or isopentane, or mixtures thereof, may be conducted in a system including a series of fixed bed reactors and a catalytic distillation reactor. The system may provide for conveyance of the fixed bed reactor effluents, without componential separation, to a downstream reactor. It has been found that a high selectivity to the dimer may be achieved even though intermediate separation of the desired product from unreacted components between reactors is not performed. Further, embodiments provide for use of a divided wall column for recovery of a high purity dimer product, reducing unit piece count and plot size.Type: GrantFiled: December 29, 2022Date of Patent: March 26, 2024Assignee: LUMMUS TECHNOLOGY LLCInventors: Rosette Barias, Liang Chen, Michael Jon Scott

Publication number: 20230365478Abstract: Processes and systems for the production of heavy isoparaffinic hydrocarbons include feeding hydrogen and a mixed isoolefin stream, including C8-C12 olefins, isoolefins, and oligomers, and C8-C12+ hydrogenated hydrocarbons to a trickle-bed reactor system. The hydrogen and mixed isoolefin are reacted over a hydrogenation catalyst, producing a liquid effluent comprising hydrogenated hydrocarbons and unreacted olefins and oligomers, and a vapor effluent comprising hydrogenated hydrocarbons, hydrogen and unreacted olefins and oligomers. The liquid effluent is fed to a first heat exchanger, producing a cooled liquid effluent stream, which is combined with the vapor effluent, producing a mixed phase effluent. The mixed phase effluent is cooled in a second heat exchanger, producing a partially condensed effluent, which is fed to a drum, producing a vent stream, a hydrogenated product stream having greater than 95 wt % C8-C12 saturated hydrocarbons, and a hydrogenated recycle stream.Type: ApplicationFiled: May 9, 2023Publication date: November 16, 2023Applicant: LUMMUS TECHNOLOGY LLCInventors: Marc Andrew Laurin, Rosette Barias, Manoj Som, Liang Chen

Patent number: 11623906Abstract: A process for supplying deaerated water to a chemical plant that includes a distillation column for separating a reaction effluent comprising water and a product. The process includes inventorying the distillation column with aerated water (water having an oxygen content of greater than 50 ppbw, such as greater than 1 ppmw). The aerated water in the distillation column may then be distilled to produce an oxygen-containing overheads and a bottoms fraction comprising deaerated water. The deaerated water in the bottoms fraction ma be transported to an upstream or a downstream unit operation, and utilizing the deaerated water in the upstream or downstream unit operation. The reaction effluent is fed to the distillation column, transitioning the distillation column from separating oxygen from water to operations for separating the product from the water.Type: GrantFiled: August 12, 2021Date of Patent: April 11, 2023Assignee: LUMMUS TECHNOLOGY LLCInventors: Rosette Barias, Maurice Korpelshoek, Michael Jon Scott, Eric Arthur Schwarz, Shahid Jamal
