The present invention provides a process for the removal of contaminants from contaminated crude oil in a vessel. An organic solvent stream is provided to the vessel containing crude oil. After mixing, an organic solvent bottom phase is allowed to form. The bottom phase comprises at least a portion of the organic solvent stream and at least a portion of the contaminants. The bottom phase is removed from the vessel, while the remaining crude oil is retained in the vessel. An aqueous stream is provided to the vessel and mixed with the remaining crude oil, allowing an aqueous bottom phase to form. The aqueous bottom phase is removed from the vessel, while the remaining crude oil is retained in the vessel.

A process for liquid-liquid extraction of an oil-blend of non-uniform oligomeric and polymeric components comprising: (a) preselecting a desired molecular weight (Mw) boundary between heavy and light components; (b) selecting an extractive solvent or an extractive mixture of solvents, which form essentially a single phase with the light components; (c) mixing the oil-blend and the extractive solvent or extractive mixture of solvents selected in step (b) at elevated temperature, which is at least at or above said fractionation temperature, and wherein the extractive solvent/mixture of solvents to oil-blend ratio is from 1:2 to 100:1; (d) allowing a phase split to form between the heavy components fraction and the light components/extractive solvent fraction at the fractionation temperature or at most 10° C. below the fractionation temperature; (e) followed by separation of said fractions.

Embodiments of the disclosure include processes for ring-opening of hydrocarbon species comprising aromatic and cycloparaffinic rings in hydrocarbon feeds to produce ring-opened products. In particular, the process comprises contacting hydrocarbon species comprising aromatic and cycloparaffinic rings with hydrogen in the presence of a ring-opening catalyst comprising a noble metal on a low-acidity crystalline material containing external pockets to facilitate ring-opening of the hydrocarbon species comprising aromatic and cycloparaffinic rings. The processes are useful in the transformation of polynuclear aromatic hydrocarbons (PAHs) to ring-opened products.
