  • Patent number: 10920152
    Abstract: Heavy hydro-carbonaceous materials such as bitumen are upgraded in supercritical water in a continuous-flow reactor system. The present invention provides a reactor arrangement for and a method of converting bitumen and other highly viscous hydrocarbon containing materials into pumpable liquids to enable further processing of such materials while avoiding production of char. The process can be carried out in an underground reactor based on oil well technology. The reactor design and method facilitates mass transfer to dissolve bitumen in heated water and breaks down heavy hydrocarbons by controlling the temperature and pressure in zones within the flowing stream. The reactor may include an embedded electric heater.

  • Patent number: 10913903
    Abstract: A system and method for separating bitumen and condensate extracted from separating bitumen from oil sands material is disclosed. The method includes passing the mixture of bitumen and condensate through a flash evaporator to separate them. In the flash evaporator the mixture is heated at high pressure after which it is sprayed into a tank where the pressure is much lower, allowing the condensate to vaporize and the bitumen to settle to the bottom of the tank. The vapors are then passed through a condenser unit, causing them to cool and liquefy.

  • Patent number: 10899993
    Abstract: An immersion extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, a final bed deck extends from below a solvent level maintained in the housing to above the solvent level such that solids material is conveyed out of the solvent pool and toward a feed outlet at the end of extraction. The bed deck may include a drainage section positioned between the top of the solvent level in the extractor and the feed outlet, allowing solvent to drain out of the solids material before being discharged through the feed outlet, thereby increasing the efficiency of the extraction process.

  • Patent number: 10895229
    Abstract: The present disclosure relates to a fuel filter (1) for filtering diesel fuel supplied to an internal combustion engine (2). The fuel filter (1) includes a filter element (12, 19) for trapping and decomposing precipitates suspended in the diesel fuel. An solid acid catalyst like a zeolite is provided for decomposing precipitates trapped by the filter element (12, 19). Sterol glycosides (precipitates) are splitted into sterol and glycoside moieties, which are soluble in the biodiesel, thus preventing clogging of the filter by sterol glycoside agglomerates. The sterol and glycoside moieties pass to the engine where they are burnt. The present disclosure also relates to a method of filtering diesel fuel for supply to an internal combustion engine (2).

  • Patent number: 10883056
    Abstract: Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

  • Patent number: 10883054
    Abstract: A method comprises correlating—in a system which comprises a non-aqueous phase comprising a hydrocarbon fluid, and an aqueous phase—partitioning levels of a basic contaminant and/or an acid of interest into the aqueous phase with the pH of the aqueous phase. The partitioning levels of the basic contaminant and the acid of interest, as well as the pH of the aqueous phase, are obtained under conditions which are representative of those used in a partitioning process in which a basic contaminant is removed from a hydrocarbon fluid. The correlations may be used in a method for selecting an acidic environment for use in a partitioning process, for estimating corrosion risk downstream of a partitioning process, or for controlling a partitioning process.

  • Patent number: 10876052
    Abstract: A hydrogen sulfide (H2S) scavenging system for removing H2S, mercaptans, and/or other sulfur-containing compounds from a natural gas stream. A co-current contacting system is located in-line within a pipe and receives the natural gas stream and a liquid scavenger stream. The co-current contacting system includes a co-current contactor including a droplet generator and a mass transfer section. The droplet generator generates droplets from the liquid scavenger stream and disperses the droplets into the natural gas stream. The mass transfer section provides a mixed, two-phase flow having a vapor phase and a liquid phase. The liquid phase includes the liquid scavenger stream with H2S, mercaptans, and/or other sulfur-containing compounds absorbed from the natural gas stream, and the vapor phase includes the natural gas stream. A separation system separates the vapor phase from the liquid phase.

  • Patent number: 10870802
    Abstract: Methods for operating a system having two downflow high-severity FCC units for producing products from a hydrocarbon feed includes introducing the hydrocarbon feed to a feed separator and separating it into a lesser boiling point fraction and a greater boiling point fraction. The greater boiling point fraction is passed to the first FCC unit and cracked in the presence of a first catalyst at 500° C. to 700° C. to produce a first cracking reaction product and a spent first catalyst. The lesser boiling point fraction is passed to the second FCC unit and cracked in the presence of a second catalyst at 500° C. to 700° C. to produce a second cracking reaction product and a spent second catalyst. At least a portion of the spent first catalyst or the spent second catalyst is passed back to the first FCC unit, the second FCC unit or both.
