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 demethanizer.

Abstract: A mixed ester composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content mixed ester or by deducting from a recycle inventory a recycle content value applied to a mixed ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a mixed ester 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 recycle content glycol ether or glycol ether ester and method of making a recycle content glycol ether or glycol ether ester wherein the recycle content is derived directly or indirectly from the cracking of recycle content pyrolysis oil and/or gas. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.

IPC: C10G9/36
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. More specifically cracking the cracker feedstock in said cracker furnace to provide an olefin-containing effluent stream; wherein the hydrocarbon composition is predominantly ethane.

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: 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.
