Abstract: In a hydrocracking process, the hydrocarbon feed is processed by a guard reactor operating at maximum severity temperatures. The processing in the guard reactor maximizes the removal of metals and performs hydrodenitrogenation steps and hydrodesulfurization steps. The demetallized and partially desulfurized and denitrogenized hydrocarbon feed is then sent to a treating reactor for further hydrodenitrogenation and hydrodesulfurization before being sent further downstream for further hydrocracking processing.
Abstract: A static mixer for desalting a fluid is disclosed. A static mixer can include a housing, a reduction cone disposed concentrically within the housing; and an expansion cone disposed concentrically within the housing; wherein the static mixer is configured to direct fluid flow through the reduction cone onto the expansion cone, thereby mixing the fluid.

Abstract: Rotary valves are adapted to replace traditional slide valves in fluid catalytic cracking units (FCCUs) such as regenerated catalyst valves, spent catalyst valves, cooled catalyst valves, and recirculation catalyst valves. The rotary valves as discussed herein are significantly more compact than a slide valve having a similar flow capacity. The rotary valve is better adapted to provide flow control or throttling than slide valves are. Flow control or throttling occurs with greater response and precision in response to control inputs and rotation. In addition to the size reduction achieved with the rotary valve, the required controls and/or hydraulic fluid necessary to achieve flow changes are significantly reduced, further saving costs for the valve, as hydraulic power units are not required. The omission of a hydraulic power unit also reduces the size of the valve and/or its accompanying structures within the FCCU.

The Product Heavy Marine Fuel Oil has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process for conducting the process is disclosed that can utilize a modular reactor vessel contained within a frame work based on ISO 40 foot or ISO 20 foot container dimensions.

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.

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.
Abstract: A process for producing olefins comprising introducing a steam cracker feed to a liquid steam cracker furnace section to produce a steam cracker product comprising olefins, and wherein an amount of olefins in the steam cracker product is greater than in the steam cracker feed; separating the steam cracker product in a separation unit into a hydrogen stream, a methane stream, an olefin gas stream (ethylene and propylene), a saturated gas stream (ethane and propane), a hydrocarbons gas stream (C4-5 hydrocarbons), an aromatics stream (C6-8 aromatic hydrocarbons), a raffinate stream (C6-8 non-aromatic hydrocarbons), and a heavies stream (C9+ hydrocarbons); feeding the hydrocarbons gas stream and hydrogen to one or more hydroprocessing reactors to produce a hydrocracking product comprising ethane and propane; and recycling the hydrocracking product and the saturated gas stream to the liquid steam cracker furnace section.
Abstract: A process and apparatus for hydrocracking a hydrocarbon stream that strips a liquid hydrocracked stream in a stripping column to provide a stripping overhead stream and a stripped stream. The stripping overhead stream fractionated to provide a light fractionated overhead stream, a light fractionated intermediate stream and a light fractionated bottoms stream in a single light fractionation column omitting the need for a separate deethanizer column.
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.
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).

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.
