    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.

  • Publication number: 20230002524
    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.

  • Publication number: 20220403259
    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.
