  • Patent number: 10550340
    Abstract: A refinery built around a slurry phase hydrocracking process unit, such as a Veba Combi-Cracker (VCC), is simpler, produces more liquid product as transportation fuels and has much higher net cash margin than a refinery built around a coker or other bottoms upgrading processes. The VCC unit replaces one or more processing steps normally included in refineries as separate and distinct processing units including heavy distillate/gas oil cracking and optionally bottoms upgrading and deep desulfurization of diesel and gasoline range cuts. The refinery design is especially suited for heavy crude upgrading and can be tuned to provide a wide range of gasoline to distillate production ratios. The refinery design is “bottomless” in the sense that it produces no heavy fuel oil or asphalt as product and no solid fuel (e.g., petroleum coke).

  • Patent number: 10113122
    Abstract: The present disclosure provides a process that employs glycerol and a catalyst for partial transformation of heavy petroleum oils to lighter hydrocarbon liquids under mild conditions without the need of external hydrogen gas. The process uses industrially produced glycerol to upgrade heavy crudes; hydrogenates aromatics to paraffin and/or olefins without the use of external hydrogen gas; operates at mild operating conditions; and employs inexpensive catalysts. This process is completely different from the hydroconversion process where high pressurized hydrogen gas is essential. The present process requires no pressurized hydrogen gas and can significantly reduce both operating and capital costs of the traditional hydrotreating process.

  • Patent number: 9771527
    Abstract: A method for upgrading a petroleum feedstock using a supercritical water petroleum upgrading system includes introducing the petroleum feedstock, water and an auxiliary feedstock. The method includes operating the system to combine the petroleum feedstock and the water to form a mixed petroleum feedstock and introducing separately and simultaneously into a lower portion of an upflowing supercritical water reactor. The auxiliary feedstock is introduced such that a portion of a fluid contained within the upflowing reactor located proximate to the bottom does not lack fluid momentum. An embodiment of the method includes operating the supercritical water petroleum upgrading system such that the upflowing reactor product fluid is introduced into an upper portion of a downflowing supercritical water reactor. The supercritical water petroleum upgrading system includes the upflowing supercritical water reactor and optionally a downflowing supercritical water reactor.

  • Patent number: 9732284
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The slurry hydrocracking reaction can be controlled by measuring the production of mesophase using X-ray diffraction. Upon a mesophase yield fraction reaching a predetermined level, reaction conditions should be moderated to avoid excessive coke production.

  • Patent number: 9732288
    Abstract: A process and apparatus are disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit share the same recycle gas compressor. A make-up hydrogen stream may also be compressed in the recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product.

  • Patent number: 9687804
    Abstract: A process for upgrading residuum hydrocarbons including: feeding pitch, hydrogen, and a partially spent catalyst recovered from a hydrocracking reactor to an ebullated bed pitch hydrocracking reactor; contacting the pitch, hydrogen, and the catalyst in the ebullated bed pitch hydrocracking reactor at reaction conditions of temperature and pressure sufficient to convert at least a portion of the pitch to distillate hydrocarbons; and separating the distillate hydrocarbons from the catalyst. In some embodiments, the process may include selecting the ebullated bed pitch hydrocracking reactor reaction conditions to be at or below the level where sediment formation would otherwise become excessive and prevent continuity of operations.

  • Patent number: 9644455
    Abstract: A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60° C. to about 200° C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260° C. to about 400° C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes.

  • Patent number: 9617484
    Abstract: Methods and apparatuses are provided for hydrotreating hydrocarbons. A method includes heating a start-up oil in a stripper liquid fraction heat exchanger during a start-up period, and heating a reactor with the start-up oil. The start-up oil is discharged from the reactor when the start-up period ends, and a standard operating period begins after the start-up period. A reactor effluent is produced by introducing a hydrocarbon stream into the reactor during the standard operating period, where hydrogen sulfide is produced from an organic sulfur compound in the hydrocarbon stream. Steam is produced in the stripper liquid fraction heat exchanger during the standard operating period.
