Publication number: 20230211331Abstract: A fluidized catalytic reactor connected to a start-up heater is provided. The start-up heater provides sufficient heat to a catalyst containing stream to gradually increase the feed temperature. This allows for a critical volumetric flow rate to be achieved so that catalyst can be recovered from product instead of being entrained in product.Type: ApplicationFiled: December 30, 2021Publication date: July 6, 2023Inventors: Richard A. Johnson, II, John J. Senetar, Sathit Kulprathipanja, Adam J. Kanyuh

Publication number: 20230203385Abstract: A start-up method for contacting a feed stream with fluidized catalyst is disclosed. The start-up method comprises reacting a feed stream over a catalyst to produce a gas stream and spent catalyst. The gas stream is separated from the spent catalyst. The separated gas stream is passed to a compressor. The operating condition associated with the compressor is measured. Based on the measured operating condition associated with the compressor, one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream is provided to the compressor to meet a predetermined operating condition associated with the compressor.Type: ApplicationFiled: October 20, 2022Publication date: June 29, 2023Inventors: Steven C. Kozup, Michael R. Van de Cotte, Adam J Kanyuh

Patent number: 11447707Abstract: A process for recovering hydrogen from dehydrogenation reactor effluent is disclosed. A feed stream comprising hydrocarbons and hydrogen to a dehydrogenation reactor maintained at dehydrogenation conditions to provide a dehydrogenation reactor effluent. The dehydrogenation reactor effluent is passed to a cold box separation unit to provide a liquid hydrocarbon product stream and a recycle hydrogen stream. A return portion of the recycle hydrogen stream is passed to the reactor effluent compressor. The subject matter disclosed improved process and apparatus which enables the paraffin dehydrogenation reactor to run at reduced H2/HC ratio without requiring an investment in a resized compressor or resized turboexpanders or separators in the cold box.Type: GrantFiled: December 22, 2020Date of Patent: September 20, 2022Assignee: UOP LLCInventor: Adam J Kanyuh

Patent number: 10584081Abstract: A process is presented for the recovery of solvent used in an alkylation process. The solvent removes heavy hydrocarbons from a C4 stream. The C4 stream is passed to an alkylation unit to generate an alkylate product. A portion of the solvent is carried over with the C4 stream and needs to be recovered to reduce the aromatics content in the C4 stream, to reduce any deleterious effects of the aromatics in downstream processing.Type: GrantFiled: May 8, 2017Date of Patent: March 10, 2020Assignee: UOP LLCInventors: Raul Zavala, Charles P. Luebke, Adam J. Kanyuh

Patent number: 10315971Abstract: Systems and processes for heat recovery associated with the separation of hydrocarbon components. Two compressors are used to compress a portion of an overhead vapor stream from a fractionation column. A pressure of the liquid portion of the compressed overhead is reduced and used to recover heat from an overhead of another separation zone having a fractionation column. Once the heat has been recovered the stream is recompressed. The recovered heat may be removed from the recompressed stream in a reboiler of another fractionation column. The fractionation columns may comprise a deethanizer stripper, propane-propylene splitter, and a depropanizer column.Type: GrantFiled: November 15, 2017Date of Patent: June 11, 2019Assignee: UOP LLCInventors: Stephen T. King, Michael R. Van de Cotte, Adam J. Kanyuh, Steven C. Kozup

Patent number: 10214695Abstract: A process for recovering heat from the separation of hydrocarbons. The overhead vapor stream from a fractionation column is passed to a two stage heat pump compressor. The first stage of compression is used to reboil the fractionation column. The second stage is compressed and cooled passed to a separation zone. The liquid in the separation zone may be passed back to the fractionation column as secondary reflux, and/or recovered as liquid product. Heat may also be removed from the second stage. A suction drum on the first stage may be used to protect the heat pump compressor from any droplets in the overhead stream.Type: GrantFiled: July 29, 2014Date of Patent: February 26, 2019Assignee: UOP LLCInventors: Stephen T. King, Adam J. Kanyuh, Xin X. Zhu

Patent number: 9809662Abstract: Processes for producing a polypropylene product by using a lower purity propylene stream. An operating parameter of the separation zone for a dehydrogenation zone effluent may be adjusted or controlled to lower the purity of the propylene stream produced by the separation zone. The reflux rate of propylene-propane splitter may be reduced. The duty of the reboiler for the propylene-propane splitter may be lowered. The number of stages in the propylene-propane splitter may be decreased.Type: GrantFiled: June 2, 2015Date of Patent: November 7, 2017Assignee: UOP LLCInventors: Adam J. Kanyuh, Michael J.
