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: 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: The present invention provides compositions comprising cellulose fibers and cellulose ester fibers and wet laid articles made from the compositions, as well as wet laid processes to produce these compositions. More specifically, the present invention provided compositions comprising cellulose fibers and cellulose acetate fibers and wet laid articles made from these compositions as well as wet laid processes to produce these compositions. The present invention also relates to developing a composition, process, wet laid product, or articles exhibiting any one of many desired benefits. Specifically, a wet laid process comprising a process that allows the quantity of water removed from a web passed through press rolls is increased relative to a web made from a 100% cellulose comparative composition.

Abstract: A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. The recycled cellulose pulp containing co-refined re-cycled cellulose fibers and cellulose ester staple fibers can be added to a hydropulper and fed back through a refiner to make wet laid products.

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.

The articles are suitable in a wide array of end uses, including as cups, lids, boxes or pouches, storage containers, trays, plates, food trays, cutlery, coffee cups, coffee cup lid, packaging, bowls, clam shells, bottle caps, straws, covers, and packaging inserts.

Abstract: A process for producing recycle polyesters made from organic compounds, e.g., acids and alcohols, derived from recycled, reused or other environmentally favored raw materials by obtaining a recycle monomer composition derived directly or indirectly from cracking a recycle content pyrolysis oil composition and reacting the recycle monomer with recycle DMT obtained directly or indirectly from the depolymerization of terephthalate polyesters to prepare a recycle polyester.

Abstract: Absorbent wet laid products are made containing cellulose fibers and cellulose ester staple fibers that are co-refined to obtain products and articles that have improved water absorbency and tensile strength or burst strength or both. The absorbent wet laid products can now be made with a synthetic fiber in the wet laid operation since cellulose ester can be subjected to a refining operation.
