  • Publication number: 20240117262
    Abstract: 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.

  • Patent number: 11905468
    Abstract: Assemblies and methods to enhance control of a fluid catalytic cracking (FCC) processing assembly associated with a refining operation, may include supplying a hydrocarbon feedstock to one or more first processing units associated with the refining operation. The assemblies and methods also may include conditioning a hydrocarbon feedstock and unit material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more FCC process controllers based at least in part on the hydrocarbon feedstock properties and the unit material properties, the FCC processing assembly, so that the prescriptively controlling results in enhancing accuracy of target content of materials produced by the FCC processing assembly, thereby to more responsively control the FCC processing assembly to achieve material outputs that more accurately and responsively converge on target properties.

  • Patent number: 11898109
    Abstract: Assemblies and methods to enhance hydrotreating and fluid catalytic cracking (FCC) processes associated with a refining operation, during the processes, may include supplying a hydrocarbon feedstock to a cat feed hydrotreater (CFH) processing unit to produce CFH unit materials. The assemblies and methods also may include conditioning material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more FCC process controllers, based at least in part on the material properties, a FCC processing assembly, so that the prescriptively controlling results in causing the processes to produce CFH materials, intermediate materials, the unit materials, and/or the downstream materials having properties within selected ranges of target properties, thereby to cause the processes to achieve material outputs that more accurately and responsively converge on one or more of the target properties.

  • Publication number: 20230416624
    Abstract: Systems and methods to provide renewable transportation fuels for internal combustion engines by converting renewable feedstocks into two or more intermediate hydrocarbon blend stocks and blending at least two of the two or more intermediate hydrocarbon blend stocks to produce the renewable transportation fuel. Methods and/or processes may include selecting sugar from a sugar source and introducing the sugar into one or more reactors. The sugar may be converted into an intermediate renewable hydrocarbon blend stock and sent to a separation unit to separate out an intermediate renewable gasoline unit. The process may include selecting and converting a lipid from a lipid source into a renewable diesel product. The renewable diesel product may be sent to a second separation unit to separate out renewable diesel and a low-grade naphtha. The low-grade naphtha and intermediate renewable gasoline may be blended to define a finished renewable gasoline.

  • Publication number: 20230416615
    Abstract: Systems and methods for enhancing the processing of hydrocarbons in a FCC unit by introduction of the coked FCC catalyst from the FCC reactor and a renewable feedstock to the FCC regenerator to facilitate regeneration of the coked FCC catalyst. The renewable feedstock can contain biomass-derived pyrolysis oil. The biomass-derived pyrolysis oil and coke from the coked FCC catalyst are oxidized by oxygen to provide a regenerated catalyst that is recycled to the FCC reactor.

  • Publication number: 20230332056
    Abstract: Methods and systems for enhancing hydrocarbon processing in a fluid catalytic cracking (FCC) unit by introducing a renewable feedstock into the FCC unit at alternative locations of the FCC unit to increase residence time and promote a higher degree of FCC feedstock cracking. The renewable feedstock may include one or more of plastic-derived pyrolysis oil or plastic-derived hydrocarbons, biomass-derived pyrolysis oil, municipal waste-derived pyrolysis oil, vegetable based feedstock, animal fat feedstock, algae oil, sugar-derived hydrocarbons, or carbohydrate-derived hydrocarbons. The alternative locations of the FCC unit may include one or more of FCC reactor catalyst bed, an FCC catalyst stripper, at a nozzle located downstream of a gas oil injection point, or at a nozzle located upstream of the gas oil injection point.

  • Publication number: 20230332058
    Abstract: Systems and methods are disclosed for enhancing the processing of hydrocarbons in a FCC unit by introduction of fluidized plastic at one or more locations of the FCC unit. In an embodiment, the method may include passing a coked FCC catalyst from a cyclone of the FCC unit to a regenerator. The method may include introducing at least oxygen and a fluidized plastic into the regenerator. The method may include combusting a combination of the fluidized plastic and a coke from the coked FCC catalyst in the regenerator, thereby to oxidize via the oxygen and produce a regenerated FCC catalyst and a flue gas. The method may include supplying the regenerated FCC catalyst from the regenerator to a riser of the FCC unit to crack the gas oil supplied to the riser of the FCC unit.
