Patent number: 12215283Abstract: Recycle content pyoil is cracked in a cracker furnace to make olefins and the coil outlet temperature of the r-pyoil fed coils can be 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.

Patent number: 12195680Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. Hydrotreatment of the oxygenated feedstock occurs in a first hydrotreating bed arranged downstream of a polishing bed. A gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed arranged upstream of the first hydrotreating bed together with fresh hydrogen. The process effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation, and the arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen. Part of the product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor.Type: GrantFiled: March 19, 2024Date of Patent: January 14, 2025Assignee: NESTE OYJInventors: Ville Suntio, Olli Visuri, Petri Lindqvist

Patent number: 12151188Abstract: Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having reduced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows selective recovery of propane from a mixture of propane and ethane.Type: GrantFiled: February 3, 2022Date of Patent: November 26, 2024Assignees: Eastman Chemical Company, North Carolina State UniversityInventors: Ashfaq Shahanawaz Shaikh, Thomas Allen Puckette, Scott Allen Owens, Syed Mohammed Maaz, Jack R.
