Abstract: A poly(vinyl acetal) composition, such as a poly(vinyl butyral) composition or resin, can be made containing recycle content by the use of a recycle content aldehyde composition as a feedstock to make the PVA or by application of a recycle allotment, such as an allocation or credit, applied to either the aldehyde composition or to the PVA composition. The recycle content is obtained by cracking a recycle content pyrolysis oil to make a variety of olefins, such as propylene or ethylene.

Abstract: Ethylene oxide composition having a recycle content value is obtained by reacting an ethylene stream containing recycle content ethylene to make a recycle content ethylene oxide or by deducting from a recycle inventory a recycle content value applied to ethylene oxide composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by ethylene oxide M manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil. An alkylene diol composition and/or an alkylene diol polyester composition having a recycle content value that is obtained by reacting a recycle content feedstock to make a recycle content alkylene diol or alkylene diol polyester or by deducting from a recycle inventory a recycle content value applied to an alkylene diol composition and/or alkylene diol polyester. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alkylene diol or alkylene diol polyester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

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: 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: 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.

Abstract: Processes and facilities for providing recycled content hydrocarbon products (r-products) from separation of pyrolysis gas formed by pyrolyzing waste plastic are provided. 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: 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). The r-olefin may then be further separated into product streams in a separation zone downstream of the cracker furnace. In some cases, presence of recycle content hydrocarbons may facilitate more efficient operation of one or more distillation columns in the separation zone, including the deethanizer and ethylene fractionator.

Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, using a cracker furnace having enhanced coil design. In some cases, the design of the furnace may prevent coking, so that the run length of the furnace is longer than conventional cracking furnaces. Cracker feed streams to the furnace can include recycle content pyrolysis oil and may be used to form olefin-containing effluent stream having recycle content.
