A system for upgrading heavy hydrocarbon feeds, such as crude oil, include a hydrotreating unit, a hydrotreated effluent separation system, a solvent-assisted adsorption system, and a hydrocracking unit. Processes for upgrading heavy hydrocarbon feeds include hydrotreating the hydrocarbon feed to produce a hydrotreated effluent that includes asphaltenes, separating the hydrotreated effluent into a lesser boiling hydrotreated effluent and a greater boiling hydrotreated effluent comprising the asphaltenes, combining the greater boiling hydrotreated effluent with a light paraffin solvent to produce a combined stream, adsorbing the asphaltenes from the combined stream to produce an adsorption effluent, and hydrocracking the lesser boiling hydrotreated effluent and at least a portion of the adsorption effluent to produce a hydrocracked effluent with hydrocarbons boiling less than 180° C. The systems and processes increase the hydrocarbon conversion and yield of hydrocarbons boiling less than 180° C.

An aspect of the present disclosure relates to a process for solvent deasphalting dearomatization, said process including: effecting deasphaltenation of a heavy oil feed by contacting the feed with a paraffinic rich solvent, optionally, in presence of a FCC catalyst to obtain a deasphalted oil rich stream, said paraffinic rich solvent being untreated naphtha; contacting the DAO rich stream with a second solvent to obtain a raffinate stream rich in non-asphaltene and non-aromatic contents and a solvent rich stream; contacting the raffinate stream with water in a first decanter to obtain a first stream rich in aromatic-lean fraction and a second stream rich in the second solvent and water; subjecting the first stream to distillation to recover the paraffinic rich solvent and to obtain deasphalted oil; contacting the solvent rich stream with water in a second decanter to obtain an aromatic rich fraction and a third stream rich in the second solvent and water; and subjecting the second stream and the third stream to distillation to recover the second solvent and water.

Fouling in a refinery vessel, such as heat transfer equipment, used in a petroleum refinery operation and in which a refineable petroleum feedstock is at an elevated temperature and in fluid communication with the refinery vessel during a petroleum refinery operation, is reduced by providing in the refineable petroleum feedstock an additive comprising (i) a poly(butylenyl)benzene sulphonic acid; or, (ii) a poly(propylenyl)benzene sulphonic acid; or, (iii) a combination of a poly(butylenyl)benzene sulphonic acid and a poly(propylenyl)benzene sulphonic acid.

The capacity of a crude oil to solvate and/or disperse asphaltenes is increased by providing a crude oil which includes an additive comprising (i) a poly(butylenyl)bezene sulphonic acid; or, (ii) a poly(propylenyl)benzene sulphonic acid; or, (iii) a combination of a poly(butylenyl)bezene sulphonic acid and a poly(propylenyl)benzene sulphonic acid.

An ebullated bed hydroprocessing system is upgraded and operated at modified conditions using a dual catalyst system to produce less fouling sediment. The less fouling sediment produced by the upgraded ebullated bed reactor reduces the rate of equipment fouling at any given sediment production rate and/or concentration compared to the sediment produced by the ebullated bed reactor prior to upgrading. In some cases, sediment production rate and/or concentration are maintained or increased, after upgrading the ebullated bed reactor, while equipment fouling is reduced. In other cases, sediment production rate and/or concentration are increased, after upgrading the ebullated bed reactor, without increasing equipment fouling. In some cases, sediment production rate and/or concentration are decreased by a given percentage, after upgrading the ebullated bed reactor, and the rate of equipment fouling is decreased by a substantially greater percentage.

A processing facility is provided. The processing facility includes an asphaltenes and metals (AM) removal system configured to process a feed stream to produce a power generation stream, a hydroprocessing feed stream, and an asphaltenes stream. A power generation system is fed by the power generation feed stream. A hydroprocessing system is configured to process the hydroprocessing feed stream to form a gas stream and a liquid stream. A hydrogen production system is configured to produce hydrogen, carbon monoxide and carbon dioxide from the gas feed stream. A carbon dioxide conversion system is configured to produce synthetic hydrocarbons from the carbon dioxide, and a cracking system is configured to process the liquid feed stream.

An example system for co-liquefying feedstock and yellow grease includes: a feedstock container to contain a feedstock; a yellow grease container to contain a yellow grease; a hydrothermal liquefaction system configured to receive feedstock from the feedstock container and to receive yellow grease from the yellow grease container; the feedstock received by the hydrothermal liquefaction system and the yellow grease received by the hydrothermal liquefaction system to become a mixture; a controller connected to the feedstock container and the yellow grease container, the controller configured to control the amount of the feedstock supplied from the feedstock container to the hydrothermal liquefaction system, the controller further configured to control the amount of the yellow grease supplied from the yellow grease container to the hydrothermal liquefaction system to be between 10% to 50% of the mixture; and a collector configured to receive a bio-crude from the hydrothermal liquefaction system.

The present invention is related to the use of ethylene alkanoate-alkyl acrylate bipolymers with a high randomness monomers distribution, which are synthesized by semicontinuous emulsion polymerization process, characterized because it is carried out using slow addition rate of the pre-emulsion feeding ({dot over (q)}≤0.009 kg.Math.L.sup.−1.Math.min.sup.−1), stabilized this last one by alkyl glycol ether type surfactants, at temperatures higher than 75° C. and with solids contents above 25 wt %, which avoids the formation of large sequences (blocks) of a same monomer. This structural characteristic gives the ethylene alkanoate-alkyl acrylate bipolymers a high efficiency as chemical agents for removal of complex water/crude oil emulsions of crude oil blends.

An integrated method for mesophase pitch and petrochemicals production. The method including supplying crude oil to a reactor vessel; heating the crude oil in the reactor vessel to a predetermined temperature for a predetermined amount of time; reducing asphaltene content in the crude oil by allowing polymerization reactions to occur in the reactor vessel at an elevated pressure in the absence of oxygen; producing a three-phase upgraded hydrocarbon product comprising gas, liquid, and solid hydrocarbon components, where the liquid hydrocarbon component comprises deasphalted oil and the solid hydrocarbon component comprises mesophase pitch; separating the gas, liquid, and solid hydrocarbon components; directly utilizing the liquid hydrocarbon component for petrochemicals production; and directly utilizing the solid hydrocarbon component for carbon artifact production.
