  • Patent number: 10414991
    Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

  • Patent number: 10407630
    Abstract: Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and gas oil steam cracking. Feeds to the mixed feed steam cracker include light products and naphtha from hydroprocessing zones within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline aromatics extraction zone within the battery limits. Feeds to the gas oil steam cracker include hydrotreated gas oil range intermediates from the vacuum gas oil hydroprocessing zone. Furthermore, vacuum residue is processed in a solvent deasphalting unit to produce deasphalted oil as additional feed to the gas oil hydroprocessing zone.

  • Patent number: 10407623
    Abstract: The disclosure describes a one-step liquid biphasic catalytic process for converting a carbohydrate-containing feedstock, preferably lignocellulose, to light naphtha (e.g., hexane, pentane, methyl cyclopentane, cyclohexane, etc.) in the presence of an acidic reactive aqueous phase and a redox catalyst in the organic extracting/reaction phase. The process provides a cost-effective route for producing light-naphtha components, in presence or not of deoxygenates. The light naphtha components are useful as feedstock for steam and catalytic cracking to produce value-added platform molecules like ethylene and propylene, as precursor for the synthesis of bioaromatics like benzene and as gasoline fuel feedstock, and as fuel additives (e.g., the concomitantly formed oxygenates) to improve the biological origin of carbon in the fuel.

  • Patent number: 10399002
    Abstract: A method for separating lighter components of a hydrocarbon product in a container tank includes introducing the hydrocarbon product into the container tank via an inlet located near or at the bottom of the container tank; routing the hydrocarbon product through a pipe-in-pipe conduit that is at least partially surrounded by a bulk fluid stored in the container tank; providing a vapor-liquid interface that allows efficient evaporation of the lighter components resulting in separation of the lighter components and a processed hydrocarbon product; and routing the processed hydrocarbon product into the annular space of the pipe-in-pipe conduit thereby thermally insulating incoming hydrocarbon product from the surrounding bulk fluid and eliminating or minimizing vapor liquid equilibrium shift of the incoming hydrocarbon product caused by increased head pressure and/or reduction in temperature of the incoming hydrocarbon product.

  • Patent number: 10385281
    Abstract: Systems, methods and compositions for reducing the heteroatom content of hydrocarbon feed using transition metal complexes and adsorption techniques. The transition metal complexes include titanyl, hafnyl and zirconyl complexes activated using one or more hydroperoxides or peracids. The activated adsorbents are incorporated into one or more vessels as an adsorption bed for adsorbing the heteroatoms present in hydrocarbon feeds. The systems, methods and compositions separate the heteroatoms passed through the system by contacting the adsorption compositions with the heteroatoms of the hydrocarbon feed, adsorbing the heteroatom to the adsorption material, further allowing for the retrieval of a hydrocarbon product having a reduced heteroatom content.

  • Patent number: 10385283
    Abstract: Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor severities and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.

  • Patent number: 10386018
    Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.
