Patent number: 11674090Abstract: Processes involving the use of a dry sorbent injection (DSI) unit or slurry reagent injection (SRI) unit to remove sulfur compounds form flue gas are described. Flue gas from an FCC regenerator, for example, is used to make superheated steam and saturated steam. The flue gas is then sent to a DSI unit to remove the sulfur compounds, and then to an economizer (or heat exchanger) to heat boiler feed water or combustion air. Because the temperature is not reduced as much as with a wet scrubber process, additional energy can be recovered in the economizer.Type: GrantFiled: November 30, 2021Date of Patent: June 13, 2023Assignee: Honeywell International Inc.Inventors: Jan De Ren, William J. Whyman, Richard A. Johnson, II, Jeffrey M. Knight, Anil Nivrutti Pachpande, Andrew J. Craig

Patent number: 11667858Abstract: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.Type: GrantFiled: April 22, 2022Date of Patent: June 6, 2023Assignee: MARATHON PETROLEUM COMPANY LPInventors: Richard L.

Patent number: 11649403Abstract: A method for thermally converting plastics and biomass, and especially non-recyclable waste plastic and or biomass, to primarily liquid phase hydrocarbons is a three step process comprised of hydrothermal treatment, steam cracking and coking. Plastic or plastic and biomass feedstocks are reduced in particle size to inch minus or smaller and suspended in a liquid slurry. The slurry is pumped to high pressure and heated to a temperature high enough to initiate de-polymerization. The resulting partially de-polymerized slurry is sent to a multi-phase separation system via a pressure reduction valve and thereafter subjected to steam cracking to further reduce the average molecular weight of the hydrocarbon components. The resulting gas phase hydrocarbon mixture is quenched, and naphtha, middle distillate, and heavy oils are condensed out. The residual heavy oil phase is further reduced in pressure and sent to a coker from which additional liquid hydrocarbon product is recovered.Type: GrantFiled: February 10, 2022Date of Patent: May 16, 2023Inventor: Barry Liss
