Patent number: 11939542Abstract: A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.Type: GrantFiled: September 11, 2023Date of Patent: March 26, 2024Assignee: Chevron Phillips Chemical Company LPInventors: Bruce D. Murray, Scott G. Morrison, Kenneth Fountain, Steven R. Horlacher, Vincent D. Mcgahee, Reza Khankal, David Dockter

Publication number: 20230407183Abstract: This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.Type: ApplicationFiled: August 15, 2023Publication date: December 21, 2023Applicant: Chevron Phillips Chemical Company LPInventors: Ronald G. ABBOTT, Scott G. MORRISON, Steven R. HORLACHER, Jamie N. SUTHERLAND, Bruce D. MURRAY, Jacob M. HILBRICH, Charles T. POLITO

Patent number: 11781073Abstract: This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based or fossil fuel co-feed, or as a feedstock in the absence of a petroleum-based or fossil fuel co-feed. A mass balance accounting approach is employed to attribute the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit, which permits assigning circular product credit to product streams. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways.Type: GrantFiled: November 8, 2022Date of Patent: October 10, 2023Assignee: Chevron Phillips Chemical Company LPInventors: Ronald G.

Publication number: 20230295524Abstract: A pyrolysis oil fractionation system for treating a pyrolysis oil feed includes a fractionation column, at least one treatment catalyst bed, and a plurality of distillation trays. The system further includes a condenser to receive a light fraction and produce a condensed gasoline product and a vapor, a receiver coupled to the condenser, a knockout drum, and a distillate stripper coupled to the fractionation column. A method for treating a pyrolysis oil feed includes, in a fractionating column, dehydrohalogenating, decontaminating, and/or dehydrating a pyrolysis oil feed in at least one treatment catalyst bed, and distilling the treated pyrolysis oil feed into a light fraction, a middle fraction, a heavy fraction, and a bottom fraction. The method further includes condensing the light fraction and producing a condensed gasoline product and a vapor, separating a fuel gas product from the vapor, and stripping the middle fraction to produce a distillate product.Type: ApplicationFiled: March 16, 2022Publication date: September 21, 2023Applicant: CHEVRON PHILLIPS CHEMICAL COMPANY LPInventor: Steven R.

Patent number: 11473017Abstract: Described herein are pyrolysis systems and pyrolysis processes for achieving a lighter yield slate than provided in conventional pyrolysis systems. Aspects include: recycling a gaseous pyrolysis product into the pyrolysis reactor to enhance the mixing of the pyrolysis system reactants; installing a bottoms liquid recycle stream to better mix the pyrolysis system reactants; and/or recycling at least a portion of a heavy fraction of the gaseous pyrolysis reactor effluent from a condenser system into the pyrolysis reactor liquid. These improvements can enhance the economic viability of plastic wastes to liquid and gaseous hydrocarbon products which are used for making circular chemical and polymer products.Type: GrantFiled: September 8, 2021Date of Patent: October 18, 2022Assignee: Chevron Phillips Chemical Company LPInventor: Steven R.
