  • Patent number: 11149213
    Abstract: Embodiments of the disclosure provide a system and method for producing light olefins from a crude oil. A crude oil feed is introduced to a crude distillation unit to produce a distillate fraction and a residue fraction. The distillate fraction is introduced to a non-catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. The residue fraction is introduced to a supercritical water reactor to produce an effluent stream. The effluent stream is introduced to a flash separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction is introduced to a catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. Optionally, the residue fraction is introduced to a vacuum distillation unit to produce a light vacuum gasoil fraction, a heavy vacuum gasoil fraction, and a vacuum residue fraction.

  • Patent number: 11149217
    Abstract: The invention relates to a process for converting a heavy hydrocarbon feedstock containing a fraction of at least 50% with a boiling point of at least 300° C., and containing sulfur, Conradson carbon, metals, and nitrogen, comprising at least two successive hydroconversion steps, which may be separated by an intermediate separation step, and at least one step of deasphalting a heavy fraction of the effluent resulting from the hydroconversion, with recycling at least one portion of the deasphalted oil (DAO) during the hydroconversion, downstream of the first hydroconversion step. The DAO is either recycled at the outlet thereof from the deasphalter, or after having undergone a fractionation step that produces a heavy fraction of the DAO that then constitutes the portion of the DAO that is recycled. This process makes it possible to simultaneously improve the degree of conversion and the stability of the liquid effluents.

  • Patent number: 11130920
    Abstract: Separation of asphaltenes from residual oil is carried out with naphtha as solvent. In particular, straight run naphtha obtained from the same crude oil source as the residual oil feed is used as the solvent. The mixture of deasphalted oil and solvent is passed to a hydroprocessing zone, without typical separation and recycle of the solvent back to the solvent deasphalting unit. Asphalt is separated from the residual oil (residue from atmospheric or vacuum distillation); the mixture of deasphalted oil and naphtha solvent is passed to the hydroprocessing unit.

  • Patent number: 11124714
    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: 11091709
    Abstract: A process for treatment of PFO from a steam cracking zone includes selectively hydrogenating PFO or a portion thereof for conversion of polyaromatics compounds contained in the PFO into aromatic compounds with one benzene ring to produce a selectively hydrogenated stream. The selectively hydrogenated stream is reacted in the absence of added hydrogen for selective ring opening and dealkylation to produce a dealkylated BTX+ stream. In addition, a naphtha reformer is integrated, so that the dealkylated BTX+ stream and a reformate stream are separated into BTX compounds. Optionally the PFO is separated into a first stream containing C9+ aromatics compounds with one benzene ring, and a second stream containing C10+ aromatic compounds, whereby the first stream containing C9+ aromatics compounds with one benzene ring is passed to the ring opening step, and the feed to the selective hydrogenation step comprises all or a portion of the second stream containing C10+ aromatic compounds.
