Abstract: A cracker stream is provided that contains a recycle content pyrolysis oil composition, a predominantly C5 to C22 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.60:1. The method for making olefins includes: (a) combining a predominantly C5 to C22 hydrocarbon stream with a recycle content pyrolysis oil composition (r-pyoil) to provide a combined cracker stream; and (b) cracking the combined cracker stream in a cracker furnace to provide an olefin-containing effluent stream, wherein the combined cracker stream contains steam at a steam-to-hydrocarbon ratio greater than 0.60:1. There is also provided a cracker stream including r-pyoil), a predominantly C2 to C4 hydrocarbon composition, and steam at a steam-to-hydrocarbon ratio of at least 0.20:1. Olefins can be made from this cracker stream as well.

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: 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: 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.
