Publication number: 20240010921Abstract: Processes and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Applicant: LUMMUS TECHNOLOGY LLCInventors: Sudipto Chakraborty, Daniel T. Fernald, David Guymon, Ron Herbanek, Richard John Jibb, Johnny Doyle Combs, Boddie Lynn Lindsey

Publication number: 20230227731Abstract: Systems and processes for pyrolyzing waste plastics, including, in one or more heating stages, heating a waste plastic from an initial temperature to a peak pyrolysis temperature, and, in a final pyrolysis stage, providing heat input sufficient to maintain a temperature of the waste plastic at a pyrolysis reaction temperature less than the peak pyrolysis temperature and maintaining the waste plastic at the pyrolysis reaction temperature for a time period to convert a portion of the waste plastic to a pyrolyzed product and a pitch. The process further includes recovering the pyrolyzed product and recovering the pitch.Type: ApplicationFiled: January 12, 2023Publication date: July 20, 2023Applicant: LUMMUS TECHNOLOGY LLCInventors: Sudipto Chakraborty, Liang Chen, Te-Chun Chu, Manoj Som, David Lee Guymon, Daniel T.

Patent number: 6093285Abstract: A system and process for purifying a 1,3-butadiene feedstock containing 1,3-butadiene and various impurities by first introducing the 1,3-butadiene feedstock stream to a separation column to produce an intermediate product stream containing 1,3-butadiene and residual impurities and then introducing the produced intermediate product stream through a condenser to a suitable dryer for removing residual impurities from the intermediate product stream and thereby forming a purified 1,3-butadiene stream. The separation column separates an overhead stream, containing 1,3-butadiene and impurities such as propadiene, water and oxygen, and a bottoms stream, containing impurities such as polymerization inhibitor, ethyl acetylene, 1,3-butadiene dimer, pentane and 1,2-butadiene, from the intermediate product stream which leaves the separation column in the form of a vapor side draw stream.Type: GrantFiled: August 31, 1998Date of Patent: July 25, 2000Assignee: Phillips Petroleum CompanyInventors: Daniel T.
