  • Patent number: 9738839
    Abstract: This invention relates to the conversion or hydrotreatment of petroleum or coal derived liquids in a novel ebullated-bed reactor system. The novel processing scheme results in a much simpler and less costly (investment and annual operating) ebullated-bed reaction system through the elimination of the high pressure, high temperature separator, hydrogen purification plant, and recycle gas compressor as well as a smaller hydrogen make-up compressor all resulting in substantial operational and construction efficiency.

  • Patent number: 8673135
    Abstract: The invention described herein relates to a novel process for reducing the carbon dioxide emissions from a coal and/or biomass liquefaction facility by utilizing a steam methane reformer unit in the complex designed to produce additional hydrogen which can be thereafter utilized in the process, as required for the plant fired heaters (including the SMR furnace), and for the production of plant steam. The plant light ends (C1, C2, etc.), which are normally utilized as fuel gas streams are the primary feeds to the SMR Unit along with the tail gas purge from a gasification complex within the facility.

  • Patent number: 8252169
    Abstract: This invention utilizes a novel method and set of operating conditions to efficiently and economically process a potentially very fouling hydrocarbon feedstock. A multi-stage catalytic process for the upgrading of coal pyrolysis oils is developed. Coal Pyrolysis Oils are highly aromatic, olefinic, unstable, contain objectionable sulfur, nitrogen, and oxygen contaminants, and may contain coal solids which will plug fixed-bed reactors. The pyrolysis oil is fed with hydrogen to a multi-stage ebullated-bed hydrotreater and hydrocracker containing a hydrogenation or hydrocracking catalyst to first stabilize the feed at low temperature and is then fed to downstream reactor(s) at higher temperatures to further treat and hydrocrack the pyrolysis oils to a more valuable syncrude or to finished distillate products. The relatively high heat of reaction is used to provide the energy necessary to increase the temperature of the subsequent stage thus eliminating the need for additional external heat input.

  • Patent number: 8057773
    Abstract: The invention described herein relates to a novel process that eliminates the need for post combustion CO2 capture from fired heaters (at atmospheric pressure and in dilute phase) in a petroleum refinery to achieve environmental targets by capturing CO2 in a centralized facility and providing fuel gas low in carbon to the fired heaters. It combines the pre-combustion capture of carbon dioxide with production of a hydrogen fuel source within a refinery to drastically reduce the carbon dioxide emissions of the plant. The hydrogen fuel is utilized for the process fired heaters and the fuel quality (carbon content) can be set to meet the refinery's emissions objectives. Moreover, the carbon dioxide captured can be sequestered and/or utilized for enhanced oil recovery (EOR).

  • Patent number: 7938953
    Abstract: An improved process for heavy oil conversion and upgrading and a combined method for heavy oil conversion and vacuum gas-oil treatment are described herein. The method utilizes the creation and recycle of a separate product from the vacuum still, which is thereafter recycled back to the heavy oil conversion reactor. The result is the production of a higher quality medium gas oil product relative to the overall vacuum gas oil product which is acceptable for use in a typical vacuum gas oil treatment process. Additionally, there is a higher diesel yield selectivity from the heavy oil conversion unit.

  • Patent number: 7938952
    Abstract: This invention relates to a novel integrated hydroconversion process for converting heavy atmospheric or vacuum residue feeds and also converting and reducing impurities in the vacuum gas oil liquid product. This is accomplished by utilizing two residue hydroconversion reaction stages, two vapor-liquid separators, and at least two additional distillate ebullated-bed hydrocracking/hydrotreating reaction stages to provide a high conversion rate of the residue feedstocks.

  • Patent number: 7279090
    Abstract: This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. This is accomplished by utilizing a solvent deasphalter (SDA) in the first step of the process with a C3/C4/C5 solvent such that the DAO product can thereafter be processed in a classic fixed-bed hydrotreater or hydrocracker. The SDA feed also includes recycled stripper bottoms containing unconverted residue/asphaltenes from a downstream steam stripper unit. The asphaltenes from the SDA are sent to an ebullated-bed reactor for conversion of the residue and asphaltenes. Residue conversion in the range of 60-80% is achieved and asphaltene conversion is in the range of 50-70%. The overall residue conversion, with the DAO product considered non-residue, is in the range of 80 W %-90 W % and significantly higher than could be achieved without utilizing the present invention.

  • Patent number: 7214308
    Abstract: This invention relates to a novel method for economically processing vacuum residue from heavy crude oils by selectively processing the difficult and easy components in reactors whose design and operating conditions are optimized for the specific feed. The process utilizes an integrated solvent deasphalting (SDA)/ebullated-bed design wherein the heavy vacuum residue feedstock is initially sent to an SDA unit operated with C4/C5 solvent to achieve a high deasphalted oil (DAO) yield. The resulting SDA products, namely asphaltenes and DAO are separately treated in ebullated-bed reactor(s) systems whose design and operating conditions are optimized for a particular feedstock. The resulting net conversion, associated distillate yield and product qualities are greatly improved relative to treatment of the entire residue feedstock in a common ebullated-bed reactor system.
