5results about "Refining by solvent de-asphalting" patented technology

Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a solvent deasphalting unit, or an ebullated bed hydrocracking unit. Products from the upgrading operations may be used as feed to a steam cracker.

A process and system to deasphalt used motor oil distillate residue including VTAE the process including feeding the used motor oil distillate residue and a supercritical solvent to an asphaltene separator that outputs an overhead having deasphalted oil and a bottoms that includes pitch.

The present invention relates to a process for producing middle distillates from a feedstock comprising a residual hydrocarbon feedstock and a hydrogen-deficient feedstock. The process comprises: (a) a step of dewaxing the residual hydrocarbon feedstock to obtain a dewaxed product having at least 50% by weight of a boiling point above 550 °C and an asphaltene product; (b) a step of combining the dewaxed product with the hydrogen-deficient feedstock to produce a mixed dewaxed product, wherein the hydrogen-deficient feedstock has a hydrogen (H) content of at least 6% by weight to a maximum of 11.3% by weight; (c) a step of hydrodemetallizing at least a part of the mixed dewaxed product obtained from step (b) to produce a hydrodemetallized product; (d) a step of hydrotreating at least a part of the hydrodemetallized product obtained from step (c) to produce a hydrotreated product; (e) a step of hydrocracking at least a part of the hydrotreated product obtained from step (d) to produce a hydrocracked product; and (f) a step of subjecting at least a part of the hydrocracked product obtained from step (e) to a separation treatment to produce at least a middle distillate fraction.

An exemplary embodiment of the present disclosure provides a system and process for making fuel from fossil and non-fossil feedstocks. The system and process can include adding a reaction product of the fossil feedstock from a first ebullated bed (EB reactor to a separator, adding a deasphalted oil product from a solvent deasphaltene (SDA) extractor to a second EB reactor, adding the non-fossil feedstock to the second EB reactor, performing a catalytic reaction on the deasphalted oil product and the non-fossil feedstock in the second EB reactor to form a mixed effluent, and mixing the mixed effluent from the second EB reactor and the fossil feedstock reaction product in the separator, thereby producing unconverted heavy oil, partially converted intermediates, and hydroconverted products.

A system for steam cracking a whole crude that may include a volatilization device, a control system, a separator, and a steam pyrolysis reactor. The volatilization device may be configured to separate a vapor phase from a liquid phase. The control system may be configured to maintain a flow rate of the whole crude and steam, at an initial relative velocity of less than 30 m / s. The separator may be fluidly connected to the volatilization device and configured to separate the liquid phase into a second vapor phase, and a second liquid phase. The steam pyrolysis reactor may include a convection section and a steam pyrolysis heater section, the convection section configured to heat the vapor phase, the liquid phase, and the second vapor phase, and the steam pyrolysis heater section configured to steam crack hydrocarbons in the vapor phase thereby generating a cracked hydrocarbon product.
