Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, are provided that integrate a cracker unit with one or more other processing units. For example, in some cases, a fluidized catalytic cracking unit may be used to crack recycle content pyrolysis oil and the effluent from the FCC may be further processed in a conventional cracker unit, including its downstream separation zone, to provide recycle content hydrocarbon product stream. In other cases, a pyrolysis unit and cracking unit may be co-located and may share at least one utility, service group, boundary, conduit, energy exchange zone, and/or geographical area.

Abstract: A cracker stream is provided that contains a recycle content pyrolysis oil composition, a predominantly C5 to C22 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.60:1. The method for making olefins includes: (a) combining a predominantly C5 to C22 hydrocarbon stream with a recycle content pyrolysis oil composition (r-pyoil) to provide a combined cracker stream; and (b) cracking the combined cracker stream in a cracker furnace to provide an olefin-containing effluent stream, wherein the combined cracker stream contains steam at a steam-to-hydrocarbon ratio greater than 0.60:1. There is also provided a cracker stream including r-pyoil), a predominantly C2 to C4 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.20:1. Olefins can be made from this cracker stream as well.

Abstract: Recycled content monoethylene glycol (r-MEG) is produced using a process and system that applies physical and/or credit-based recycled content from one or more feed materials to the MEG produced from the feed materials. Recycled content diethylene glycol (DEG) can be formed in a similar manner.

Abstract: Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. Alternatively, the r-pyoil with a predominantly c8+ fraction can be fed to the cracker feed. The furnace can be a gas fed furnace, or split cracker furnace.

Abstract: A process and system for recovering a recycle content carbon dioxide is provided that can lower the carbon footprint and global warming potential of a chemical recycling facility. More particularly, a pyrolysis flue gas and/or a pyrolysis gas from waste plastic pyrolysis may be treated in an absorber system to thereby form a recovered CO2 stream comprising recycle content carbon dioxide. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the carbon dioxide recovery process and system herein.
