Abstract: A heat integration process and system for a chemical recycling facility is provided that can lower the carbon footprint and global warming potential of the facility. More particularly, one or more heat transfer media may be used to recover heat energy from a waste plastic pyrolysis effluent and redistribute the recovered heat energy throughout the chemical recycling facility. Furthermore, a staged condensation configuration may be utilized to produce multiple pyrolysis oil streams and to provide heat to the heat transfer media. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the heat integration process and system herein.

Abstract: A heat integration process and system for a chemical recycling facility is provided that can lower the carbon footprint and global warming potential of the facility. More particularly, waste plastic pyrolysis effluent may be used to provide heat energy to liquefied plastics upstream of the pyrolysis reactor by directly contacting the pyrolysis effluent and liquefied plastics. In addition, one or more heat transfer media may be used to recover heat energy from a waste plastic pyrolysis effluent and redistribute the recovered heat energy throughout the chemical recycling facility. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the heat integration process and system herein.

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: A polypropylene composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content polypropylene or by deducting from a recycle inventory a recycle content value applied to a polypropylene composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a polypropylene manufacturer has its origin in recycled waste plastics.

Abstract: Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

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: 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.

Abstract: A pyrolysis method and system are provided that utilizes a hydrogen gas or steam in order to enhance the pyrolysis oils produced from recycled plastic wastes. More particularly, the disclosed pyrolysis method and system may be configured to co-feed a hydrogen gas or steam and various types of waste plastics, including post-customer and post-industrial wastes, into a pyrolysis unit and thereby produce desirable pyrolysis oils.
