Processes and systems for producing upgraded product from residue

Embodiments of the present disclosure are directed to a process for producing upgraded product from residue comprising atmospheric residue or vacuum residue upgrading comprising separating the residue through a Solvent Deasphalting (SDA) unit, wherein the SDA unit includes an asphaltene separator that separates the residue into asphaltene pitch and a stream comprising deasphalted oil (DAO) and resin, and a resin separator that subsequently separates the stream comprising DAO and resin into separate DAO and resin streams, treating the resin stream with supercritical water (SCW) to produce an upgraded resin stream, and hydroprocessing a portion of the upgraded resin stream and the DAO stream to produce the upgraded product.

An integrated hydrocracking and solvent deasphalting process that provides for removal from the heavy oil recycle stream heavy polycyclic aromatic compounds formed in the hydrocracking step and recycling the resulting deasphalted paraffinic oil as a feed to the hydrocracker reactor of the process for further conversion.

Conversion of whole crude to value added petrochemicals in an integrated reactor process

An integrated process and associated system for conversion of crude oil to value added petrochemicals. The process includes separating crude oil into light and heavy crude fractions and processing the heavy fraction in a solvent deasphalting unit and a delayed coker unit, and then providing the light fraction and selected effluents of the solvent deasphalting unit and the delayed coker unit to a hydrotreater. The process further includes separating the effluent of the hydrotreater to generate a C1 fraction passed to a methane cracker, a C2 fraction passed to an ethane steam cracker, a C3-C4 fraction passed to a dehydrogenation reactor, a hydrotreated light fraction passed to an aromatization unit, and a hydrotreated heavy fraction passed to a steam enhanced catalytic cracking unit. The process further includes separating effluents of the various unit operations into product streams including a BTX stream and a light olefin stream.

Production of hydrocarbon product and selective rejection of low quality hydrocarbons from bitumen material
10450511 · 2019-10-22 · ·

Methods are described for the production of a hydrocarbon product and selective rejection of low quality hydrocarbons from a bitumen-containing material, where product quality, production yield, processing input requirements, and environmental benefits are assessed for selecting a candidate method for deployment. The methods facilitate selection and deployment of sustainable hydrocarbon production operations rather than focusing on maximizing volumetric yield of hydrocarbons.

Hydroprocessing of heavy hydrocarbon feeds using small pore catalysts

Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 to about 120 under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

REMOVAL OF POLYNUCLEAR AROMATICS FROM SEVERELY HYDROTREATED BASE STOCKS

Adsorbents for aromatic adsorption are used to improve one or more properties of base stocks derived from deasphalted oil fractions. The adsorbents can allow for removal of polynuclear aromatics from an intermediate effluent or final effluent during base stock production. Removal of polynuclear aromatics can be beneficial for improving the color of heavy neutral base stocks and/or reducing the turbidity of bright stocks.

Process to upgrade partially converted vacuum residua

Processes for upgrading partially converted vacuum residua hydrocarbon feeds are disclosed. The upgrading processes may include: steam stripping the partially converted vacuum residua to generate a first distillate and a first residuum; solvent deasphalting the first residuum stream to generate a deasphalted oil and an asphaltenes fraction; vacuum fractionating the deasphalted oil to recover a deasphalted gas oil distillate and a heavy deasphalted residuum; contacting the first distillate and the deasphalted gas oil distillate and hydrogen in the presence of a first hydroconversion catalyst to produce a product; contacting the heavy deasphalted residuum stream and hydrogen in the presence of a second hydroconversion catalyst to produce an effluent; and fractionating the effluent to recover a hydrocracked atmospheric residua and a hydrocracked atmospheric distillate.

PROCESS AND APPARATUS FOR RECOVERING HYDROCRACKED SOFT PITCH
20190194553 · 2019-06-27 ·

Settling unconverted pitch from a SHC reactor effluent before fractionation improves efficiency of fractionation of slurry hydrocracked products. The recycle of soft pitch to the SHC reactor results in improved reactor operation by avoiding the recycle of lighter products which vaporize in the reactor to occupy reactor space and the recycle of hard pitch which will not convert. The settling step facilitated by mixing with a solvent can achieve a separation between soft pitch and hard pitch not achievable in a fractionation column.
