PROCESSES FOR UTILISATION OF PURIFIED COAL TO UPGRADE REFINERY PROCESS COMPONENTS IN THE MANUFACTURE OF PETROLEUM COKE
Processes for the production of coke, and one or more volatile products comprise the steps of: (i) providing a purified coal product (PCP), wherein the PCP is in particulate form, and wherein at least about 90% v of the particles are no greater than about 100 μm in diameter; wherein the PCP has an ash content of less than about 10% m and a water content of less than around 5% m; (ii) combining the PCP with a liquid residue oil to create a combined solid-liquid blend, wherein the solid-liquid blend comprises at least around 0.1% m and at most around 30% m PCP; (iii) subjecting the solid-liquid blend to a temperature in excess of 375° C. for a time period sufficient to induce cracking of at least 1% of the PCP particles to generate the one or more volatile products, and (iv) producing coke from the product of step (iii).
LOW SULFUR FUEL OIL BLENDS FOR STABILITY ENHANCEMENT AND ASSOCIATED METHODS
Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.
High napthenic content marine fuel compositions
Marine diesel fuel/fuel blending component compositions and fuel oil/fuel blending component compositions are provided that are derived from crude oils having high naphthenes to aromatics volume and/or weight ratios and a low sulfur content. In addition to having a high naphthenes to aromatics ratio, a low sulfur content, and a low but substantial content of aromatics, such fuels and/or fuel blending components can have a reduced or minimized carbon intensity relative to fuels derived from conventional sources. The unexpected ratio of naphthenes to aromatics contributes to the fuels and/or fuel blending components further having additional unexpected properties, including low density, low kinematic viscosity, and/or high energy density.
PROCESSES FOR UPGRADING A HYDROCARBON FEED
A process for upgrading a heavy oil includes passing heavy oil and disulfide oil to a thermal cracking system that includes a thermal cracking unit and a cracker effluent separation system downstream of the thermal cracking unit and thermally cracking at least a portion of the heavy oil in the presence of the disulfide oil in the thermal cracking unit to produce solid coke and a cracking effluent comprising reaction products. The reaction products include one or more liquid reaction products, one or more gaseous reaction products, or both. The presence of the disulfide oil in the thermal cracking unit promotes conversion of hydrocarbons from the heavy oil to the liquid reaction products, the gaseous reaction products, or both relative to the production of the solid coke.

Slurry phase reactor with internal cyclones
A system for processing a hydrocarbon feed has a final stage reactor and internal separator with cyclone that forms a substantially gas stream and a substantially non-gas stream. The substantially gas stream is sent directly from the final stage reactor and separator to further downstream processing.
Process for upgrading hydrocarbon feedstock utilizing low pressure hydroprocessing and catalyst rejuvenation/regeneration steps
Heavy hydrocarbon feedstocks including crude oil are upgraded under relatively low pressure conditions in an ebullated-bed hydroprocessing zone to remove the heteroatom containing hydrocarbons. Catalyst particles are regenerated/rejuvenated and recycled back to the ebullated-bed hydroprocessing reaction zone. The regeneration/rejuvenation is effective to restore catalytic activity while minimizing leaching of the active components(s).
Low sulfur fuel oil blends for paraffinic resid stability and associated methods
Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.
SOLVENT DEASPHALTING DEAROMATIZATION PROCESS FOR HEAVY OIL UPGRADATION
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.
