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.

Abstract: Various processes and configuration are provided for a chemical recycling facility that can lower the carbon footprint and global warming potential of the facility. More particularly, we have discovered numerous ways for reducing the carbon footprint of the facility by: (i) recycling at least a portion of the residual heat energy from the pyrolysis effluent back upstream to the pyrolysis process and waste plastic liquification stage; (ii) recovering at least a portion of the carbon dioxide from at least a portion of the pyrolysis flue gas and/or the pyrolysis gas; (iii) feeding at least a portion of the pyrolysis gas at a cracker facility at a position downstream of a cracker furnace; (iv) using at least a portion of a demethanizer overhead stream as a fuel in a pyrolysis facility and/or a cracking facility; and (v) providing a chemical recycling facility that contains a pyrolysis facility co-located with a cracking facility.

Abstract: Processes and facilities for providing recycled content hydrocarbon products (r-products) from the pyrolysis of waste plastic are provided. Processing schemes are described herein that increase energy efficiency and help reduce overall environmental impact while producing valuable final products from chemically recycled waste plastic. Use of recycled content and/or high hydrogen content fuel in one or more process furnaces also reduces global warming potential of the facility by reducing carbon emissions, while also improving energy integration.

Abstract: A mixed ester composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content mixed ester or by deducting from a recycle inventory a recycle content value applied to a mixed ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a mixed ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: The present application discloses a recycle content cracked effluent composition having a certain compositional profile produced by cracking a cracker feed comprising a recycle content pyrolysis oil composition, and methods of producing the recycle content cracked effluent composition.

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 predominantly C2 to C4 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 a first coil while a second cracker feed with none of the r-pyoil or less of the r-pyoil is fed to a second coil, and both are cracked in a cracker furnace to form an olefin-containing effluent stream. Alternatively, the r-pyoil can be fed and distributed across multiple coils along with the non-recycle cracker feed. The furnace can be a gas fed furnace, or split cracker furnace. Further, a first cracker stream with r-pyoil in a first coil can have a lower total molar flow rate than a second cracker stream in a second coil in the same furnace.

Various separation schemes may be employed to process the recycled content pyrolysis gas (r-pygas) into one or more recycled content hydrocarbon streams, which can be used in forming a variety of recycled content products.

Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). In some cases, the pyrolysis and cracking may be carried out in different sections of the same furnace, or in different furnaces in the same cracker facility. Pyrolysis conducted in a furnace may or may not require retrofitting a furnace previously used to crack alkanes to form olefins.
