Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

The Product Heavy Marine Fuel Oil has a maximum sulfur content (ISO 14596 or ISO 8754) less than 0.5 mass %. A process plant for conducting the process for conducting the process is disclosed.

Systems and methods are provided for co-processing of renewable distillate fractions with mineral fractions to produce at least a jet (or kerosene) boiling range product and a diesel boiling range product. A combination of a jet boiling range product fraction and a diesel boiling range product fraction with unexpected properties can be formed by first blending i) a distillate boiling range feed fraction containing a renewable distillate component with ii) a mineral feed fraction (possibly corresponding to a whole or partial crude oil) that includes diesel boiling range compounds to form a blended composition. The blended composition can then be fractionated to form a jet boiling range product fraction and a diesel boiling range product fraction. Optionally, the resulting jet boiling range product fraction and/or diesel boiling range product fraction can be exposed to further processing, such as hydroprocessing or catalytic cracking.

The device for preventing the formation of paraffin and asphaltene sediments and for the reduction of the viscosity of crude oil for use at an eruptive oil well, an oil well with pumpjack or for use at a pipeline, the stated device including six identical serially connected modules. Each module has an inlet spout and outlet spout. Crude oil under pressure passes through modules and simultaneously is in contact with different alloys. The device's elements consist of four different alloys that affect the crude oil while it passes through modules under pressure in the manner that it prevents the formation of paraffin and asphaltene deposits inside the pipeline or eruptive oil wells or oil wells with pumpjacks.

A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.

This disclosure relates to a procedure, which through the application of a catalyst in homogeneous phase, allows the transformation of heavy hydrocarbons (vacuum residue, atmospheric residue, heavy and extra-heavy crudes) into hydrocarbons of lower molecular weight, characterized because after its application, the hydrocarbons obtain greater API gravity, lower kinematic viscosity and different composition by hydrocarbon families (SARA) that increases the proportion of saturated and aromatic resins and asphalts. The sulphur and nitrogen content is also reduced, resulting in higher yields to high commercial value distillates and a lighter product as compared to the original crude.

Methylparaffins having limited methyl branching may be prepared by contacting at least one linear olefin with hydrogen in the presence of a dual-function supported catalyst comprising a solid acid component and a hydrogenation component under conditions sufficient to catalytically isomerize the at least one linear olefin into an intermediate product comprising one or more branched olefins, and hydrogenating the one or more branched olefins to form an isoparaffin product comprising one or more methylparaffins. Heat transfer fluids comprising such methylparaffins may be used in various thermal management systems, such as within various systems of electric vehicles, server farms, or other locales in need of efficient heat transfer.

A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

An improved process for making a base oil and for improving base oil yields by combining an atmospheric resid feedstock with a base oil feedstock and forming a base oil product via hydroprocessing. The process generally involves subjecting a base oil feedstream comprising the atmospheric resid to hydrocracking and dewaxing steps, and optionally to hydrofinishing, to produce a light and heavy grade base oil product. A process is also disclosed for making a base oil having a viscosity index of 120 or greater from a base oil feedstock having a viscosity index of about 100 or greater that includes a narrow cut-point range vacuum gas oil. The invention is useful to make Group II and/or Group III/III+ base oils, and, in particular, to increase the yield of a heavy base oil product relative to a light base oil product produced in the process.
