  • Patent number: 10717941
    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 fluid catalytic 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 and FCC naphtha aromatics extraction zone within the battery limits.

  • Patent number: 10421914
    Abstract: A method comprising a combination and sequential methods to: a.-)Produce solid vacuum residue, b.-) Melt the solid vacuum residue, and c.-)Heat the melted Solid Vacuum residue. This invention applies to any single or mixture of hydrocarbons including one or more heavy crude oils, extra heavy crude oils, tar sands and/or bitumens, (named heavy feedstocks). The heavy feedstock is processed in the production field or a nearby location using atmospheric, vacuum distillation and a solid forming unit, to produce liquid distillates and a solid vacuum residue resulting from a deep cut point of the heavy vacuum gasoil. The Solid Vacuum Residue is melted and heated at the destination to be used as feedstocks in refineries deep conversion units to optimize operations and economics.This invention reduces the diluent imports at the heavy feedstocks production fields used for its production and/or its transportation.

  • Patent number: 9809764
    Abstract: A process for producing high yields of higher quality (API Group II, Group III?) lubricating oil basestock fractions which allows the production of two or more types of high quality lubes in continuous mode (no blocked operation mode) without transition times and feed or intermediate product tankage segregation. Two consecutive hydroprocessing steps are used: the first step processes a wide cut feed at a severity needed to match heavy oil lube properties. The second step hydroprocesses a light oil after fractionation of the liquid product from the first step at a severity higher than for the heavy oil fraction. The two hydroprocessing steps will normally be carried out in separate reactors but they may be combined in a single reactor which allows for the two fractions to be processed with different degrees of severity.

  • Patent number: 7857965
    Abstract: A process for upgrading hydrocarbonaceous oil containing heteroatom-containing compounds where the hydrocarbonaceous oil is contacted with a solvent system that is a mixture of a major portion of a polar solvent having a dipole moment greater than about 1 debye and a minor portion of water to selectively separate the constituents of the carbonaceous oil into a heteroatom-depleted raffinate fraction and heteroatom-enriched extract fraction. The polar solvent and the water-in-solvent system are formulated at a ratio where the water is an antisolvent in an amount to inhibit solubility of heteroatom-containing compounds and the polar solvent in the raffinate, and to inhibit solubility of non-heteroatom-containing compounds in the extract. The ratio of the hydrocarbonaceous oil to the solvent system is such that a coefficient of separation is at least 50%.

  • Patent number: 7651605
    Abstract: When a heavy fuel oil with a sulfur content of 1 percent by mass or lower is produced from a feedstock consisting of a heavy hydrocarbon oil derived from a heavy crude oil having an API degree of 30 or less and containing sulfur and metal components in amounts larger than those of ordinary crude oil, the conventional processes requires higher reaction temperature and was accompanied with a remarkably enhanced deactivation rate of the catalyst which results in a remarkable shortened lifetime thereof. Therefore, it is regarded as substantially impossible to treat the feedstock.
