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

Publication number: 20220340820Abstract: Processes for using pyrolysis gas as a feedstock or a co-feedstock for making a variety of chemicals, for example, circular ethylene, circular ethylene polymers and copolymers, and other circular products. In these processes, pyrolysis reactor conditions can be selected to increase or optimized the production of pyrolysis gas over pyrolysis oil, and the pyrolysis gas which is usually used as fuel or flared can be fed downstream of the steam cracker furnace for economic use to form circular chemicals. Operating parameters of the pyrolysis unit may be adjusted to increase or decrease the proportion of pyrolysis gas relative to pyrolysis liquid as a function of their relative economic values.Type: ApplicationFiled: April 12, 2022Publication date: October 27, 2022Applicant: CHEVRON PHILLIPS CHEMICAL COMPANY LPInventors: Ronald G.
