    Abstract: A predominantly C 2 to C 4 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: Disclosed is a process for separating solids from liquid in a slurry. The process is characterized by using two filtration media. One filtration medium contains less than 10 mm in thickness of a filter cake containing the solids, and the other filtration medium contains at least 10 mm in thickness of a filter cake containing the solids. The second filtration medium has a higher separation efficiency that the first filtration medium. The process is particularly useful for separating terephthalic acid solids from an oxidation product slurry.

    Abstract: A process for producing a microfiber product stream, the process comprising: (A) contacting cut multicomponent fibers having a length of less than 25 millimeters with a treated aqueous stream in a fiber slurry zone to produce a cut multicomponent fiber slurry; (B) contacting the cut multicomponent fiber slurry with a heated aqueous stream in a mix zone to produce a heated multicomponent fiber slurry; (C) routing the heated multicomponent fiber slurry to a fiber opening zone to remove a portion of the water dispersible sulfopolyester to produce an opened microfiber slurry; and (D) routing the opened microfiber slurry to a primary solid liquid separation zone to produce the microfiber product stream and a first mother liquor stream.

    Abstract: Disclosed are processes and apparatus for producing a carboxylic acid. The processes employ a concentration section disposed before and/or after a product isolation section, which allows for oxidation byproducts produced in the process to exit the product isolation section with the isolated carboxylic acid product and/or to be combined with the isolated carboxylic acid product downstream of the product isolation section at a rate of at least about 15 percent of the net make rate of the oxidation byproducts in the production process.
