  • Patent number: 8685233
    Abstract: The invention relates to field of processing hydrocarbon feedstock including crude oil, wherein metals such as calcium are removed. In the face of the rising prices of crude oil, refiners are forced to process opportunity crudes such as DOBA, which pose many problems including fouling of equipment due to certain metallic salts, such as calcium napthenate. Calcium, which cannot be removed from crude oil during normal desalting process, poses very serious problems. The invention provides method for removal of calcium, wherein crude oil is mixed, with effective metal removing amount of aqueous extraction solution of an additive comprising a chemical compound selected from a group consisting of metallic acid, maleic anhydride or fumaric acid or salts or derivatives thereof, enabling separation of hydrocarboneous phase and aqueous phase containing metal ions, in crude desalter. Only hydrocarboneous phase devoid of calcium is processed further, thereby preventing fouling of equipment.

  • Patent number: 8679325
    Abstract: Embodiments of a method and a system for recovering energy, materials or both from asphaltene-containing tailings are disclosed. The asphaltene-containing tailings can be generated, for example, from a process for recovering hydrocarbons from oil sand. Embodiments of the method can include a flotation separation and a hydrophobic agglomeration separation. Flotation can be used to separate the asphaltene-containing tailings into an asphaltene-rich froth and an asphaltene-depleted aqueous phase. The asphaltene-rich froth, or an asphaltene-rich slurry formed from the asphaltene-rich froth, then can be separated into a heavy mineral concentrate and a light tailings. Hydrophobic agglomeration can be used to recover an asphaltene concentrate from the light tailings. Another flotation separation can be included to remove sulfur-containing minerals from the heavy mineral concentrate. Oxygen-containing minerals also can be recovered from the heavy mineral concentrate.

  • Patent number: 8673130
    Abstract: A hydroprocessing method and system involves introducing heavy oil and well-dispersed metal sulfide catalyst particles, or a catalyst precursor capable of forming the well-dispersed metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The well-dispersed or in situ metal sulfide catalyst particles are formed by 1) premixing a catalyst precursor with a hydrocarbon diluent to form a precursor mixture, 2) mixing the precursor mixture with heavy oil to form a conditioned feedstock, and 3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil to form the well-dispersed or in situ metal sulfide catalyst particles. The well-dispersed or in situ metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.

  • Patent number: 8658028
    Abstract: A process for removing elemental sulfur from liquid hydrocarbon steams such as transportation fuel streams, e.g. gasoline, diesel, kerosene, and jet, by contacting such streams with an immiscible aqueous solution under static mixing conditions. The aqueous solution contains a caustic and an effective amount of a Group I or Group II metal sulfide or polysulfide. The elemental sulfur in the stream is converted to a polysulfide that is not soluble in the hydrocarbon stream but is soluble in the aqueous solution, thus resulting in a hydrocarbon product stream having a substantially lower level of elemental sulfur.

  • Patent number: 8568584
    Abstract: A method is described for controlling instability of operation in a de-ethanizer tower (13) in the gas recovery unit in fluid catalytic cracking units and delayed coking units. The method comprises the step of intervening in the de-ethanizer tower (13) when instability occurs in it, and adjusting the material balance of water in such a way that the excess of water in the feed load stream (9) is removed only as an azeotrope. The intervention is performed by introducing into the feed load stream (9) of the de-ethanizer tower (13) a volume fraction (18) of a flow of hydrocarbon, which may be either dry hydrocarbons or hydrocarbons with a low level of water content.
