Abstract: Recycle content pyoil is cracked in a cracker furnace to make olefins and the coil outlet temperature of the r-pyoil fed coils can he lowered by adding r-pyoil to the cracker feedstock, or alternatively, the coil outlet temperature of the r-pyoil fed tubes can rise if the mass flow rates of the combined cracker stream containing r-pyoil are kept the same or lowered. Further, increasing the hydrocarbon mass flow rate by addition of r-pyoil can be achieved to also increase the output of ethylene and propylene in the cracker effluent. The cracker furnace can accept ethane and/or propane feedstocks in vapor form along with a liquid and/or vapor feed of r-pyoil.

Abstract: A predominantly C2 to C4 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 a first coil while a second cracker feed with none of the r-pyoil or less of the r-pyoil is fed to a second coil, and both are cracked in a cracker furnace to form an olefin-containing effluent stream. Alternatively, the r-pyoil can be fed and distributed across multiple coils along with the non-recycle cracker feed. The furnace can be a gas fed furnace, or split cracker furnace. Further, a first cracker stream with r-pyoil in a first coil can have a lower total molar flow rate than a second cracker stream in a second coil in the same furnace.

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 bale of sheets made of waste/recycle cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have: i. a denier per filament (DPF) of less than 3, or ii. a cut length of less than 6 mm, or iii. crimping, or iv. a combination of any two or more of (i)-(iii). The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper. The waste/recycle cellulose fibers and CE staple fibers can be co-refined prior to making the bale of sheets.
