  • Publication number: 20150027925
    Abstract: Methods are provided for producing a plurality of lubricant base oil products with an increased overall yield. Prior to the final hydrocracking stage for viscosity index uplift, a feed for making a lubricant base oil is fractionated in order to form at least a feed for making a lighter lubricant base oil and a feed for making a heavier lubricant base oil. The fractionation cut points are selected to so that the feed fraction for forming a light lubricant base oil has a higher Noack volatility and a lower viscosity than the desired targets for the lighter lubricant base oil. The feed fractions are then hydroprocessed separately to achieve desired properties. After hydroprocessing, a portion of the heavier base oil is blended into the light lubricant base oil to produce a blended base oil product. This returns the volatility and the viscosity of the blended base oil to the desired specifications.

  • Patent number: 8877042
    Abstract: The production of light hydrocarbons consisting of ethylene, propylene, butylenes, and of gasoline is enhanced by introducing a heavy oil feedstream derived from an external source into an ancillary downflow reactor that utilizes the same catalyst composition as an adjacent FCC unit for cracking the heavy oil and withdrawing the desired lighter hydrocarbon reaction product stream from the downflow reactor and regenerating the catalyst in the same regeneration vessel that is used to regenerate the spent catalyst from the FCC unit. The efficiency of the recovery of the desired lighter olefinic hydrocarbons is maximized by limiting the feedstream to the downflow reactor to heavy oils that can be processed under relatively harsher conditions, while minimizing production of undesired by-products.

    Abstract: Integrated processes for upgrading crude shale-derived oils, such as those produced by oil shale retorting or by in situ extraction or combinations thereof. Processes disclosed provide for a split-flow processing scheme to upgrade whole shale oil. The split flow concepts described herein, i.e., naphtha and kerosene hydrotreating in one or more stages and gas oil hydrotreating in one or more stages, requires additional equipment as compared to the alternative approach of whole oil hydrotreating. While contrary to conventional wisdom as requiring more capital equipment to achieve the same final product specifications, the operating efficiency vis a vis on-stream time efficiency and product quality resulting from the split flow concept far exceed in value the somewhat incrementally higher capital expenditure costs.

    Abstract: In an FCC process and system, a whole crude oil feedstock is directly converted into light olefins and other products. The feed is separated into a high boiling fraction and a low boiling fraction, and each fraction is processed in separate FCC downflow reactors. The catalyst, combined from both downflow reactors, is regenerated in a common vessel. The low carbon content in the catalyst particles from the low boiling fraction downflow reactor is insufficient to provide the necessary heat. By combining catalyst particles from the high boiling fraction having high carbon content helps to provide additional heat for regeneration.

The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

  • Publication number: 20130248421
    Abstract: An integrated hydroprocessing and fluid catalytic cracking process is provided for the direct processing of a crude oil to produce olefinic and aromatic petrochemicals. Crude oil and hydrogen are charged to a hydroprocessing zone operating under conditions effective to produce a hydroprocessed effluent having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity. The hydroprocessed effluent is separated into a low boiling fraction and a high boiling fraction. The low boiling fraction is cracked in a first downflow reactor of a fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst, and the high boiling fraction is cracked in a second downflow reactor of the fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst.

  • Publication number: 20130026065
    Abstract: An integrated process and system for conversion of a heavy crude oil to produce transportation fuels is provided. The process includes separating the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction. The aromatic-rich fraction is hydrocracked under relatively high pressure to convert at least a portion of refractory aromatic organosulfur and organonitrogen compounds and to produce a hydrocracked product stream. Unconverted bottoms effluent is recycled to the aromatic separation step. The aromatic-lean fraction is cracked in a fluidized catalytic cracking reaction zone to produce a cracked product stream, a light cycle oil stream and a heavy cycle oil stream. In certain embodiments the aromatic-lean fraction can be hydrotreated prior to fluidized catalytic cracking.

  • Publication number: 20120168348
    Abstract: A process for cracking a heavy hydrocarbon feed comprising a vaporization step, a catalytic cracking step, a hydrotreating step, and a steam cracking step is disclosed. The heavy hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted with a counter-current steam to produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is catalytically cracked to produce a cracked product. The cracked product is distilled to produce a overhead stream, a light cycle oil, and a heavy cycle oil. The light cycle oil is reacted with hydrogen in the presence of a catalyst to produce a hydrotreated light cycle oil. The hydrotreated light cycle oil and the overhead stream are fed to the vaporization unit.

  • Publication number: 20120152804
    Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur and organonitrogen compounds to produce a hydrocarbon product having low levels of sulfur-containing and nitrogen-containing compounds, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the refractory organosulfur and organonitrogen compounds and an aromatic-lean fraction containing a substantial amount of the labile organosulfur and organonitrogen compounds. The aromatic-lean fraction is contacted with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized organosulfur and organonitrogen compounds.
