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 pyrolysis unit and cracking unit may share a common energy exchange zone so that energy from one unit may be transferred to the other. The energy exchange may be direct or indirect and may be present at one or more locations between the units.

Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: After cellulose fibers and cellulose ester fibers are co-refined, they are fed to a blend tank continuously feeds a wet laid process. The composition in the blend tank includes co-refined cellulose fibers and cellulose ester fibers and one or more additives, and the cellulose ester fibers have a denier per filament (DPF) of less than 3, a cut length of less than 6 mm, crimped, or non-round with a DPF of less than 3.

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: The present disclosure provides a process of recovering sulfopolyester comprising reduced impurity. Sulfopolyester is recovered from a composite material comprising water-dispersible sulfopolyester polymer and at least one non-water-dispersible polymer. The process includes washing the composite material comprising water-dispersible sulfopolyester with a solvent composition. The recovered sulfopolyester can be generated as a concentrated aqueous dispersion, a polymer melt, or a sulfopolyester solid.

Abstract: A recycle content ethylene is fed to a reactor to make propionaldehyde having recycle content. The recycle ethylene feedstock is derived directly or indirectly from the cracking of recycle content pyrolysis oil. The cracking of the pyrolysis oil can be conducted in a gas furnace or a split furnace.

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. Alternatively, the r-pyoil with a predominantly C4-C7 fraction can be fed to the cracker feed. The furnace can be a gas fed furnace, or split cracker furnace.

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 particularly cracker feedstock comprises a recycle content pyrolysis oil composition (r-pyoil), wherein the cracker feedstock has a boiling point curve defined the following characteristics (i) through (iii): (i) a 90% boiling point at least 350° C.; (ii) a 10% boiling point of at least 60° C.; and (iii) a 50% boiling point in the range of from 95° C. to 200° C.
