Abstract: Processes and facilities for producing recycled chemical products from waste plastic are described herein. The processes include treating process streams, such as a pyrolysis gas stream and/or at least a portion of a cracker furnace effluent stream, in a caustic scrubber process to remove certain components, such as carbon dioxide. The spent caustic solution from the caustic scrubber process is then recycled and reused in other caustic processes within the facility, which can include a halogen neutralization process from removing halogens from a liquification process off-gas.

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: Processes and systems for making recycle content hydrocarbons, including olefins, using a cracker furnace having enhanced coil design.

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 debutanizer.
