Abstract: The invention relates to a process for the recovery of aliphatic hydrocarbons from a liquid stream comprising aliphatic hydrocarbons, heteroatom containing organic compounds and optionally aromatic hydrocarbons, involving (i) contacting said liquid stream with a washing solvent thereby removing heteroatom containing organic compounds; a) liquid-liquid extraction of the washed stream with an extraction solvent; b) mixing the extract stream, comprising extraction solvent, heteroatom containing organic com-pounds and optionally aromatic hydrocarbons, with a demixing solvent to remove additional heteroatom containing organic compounds and optional aromatic hydrocarbons; and c) separation of the remaining stream into a demixing solvent stream and an extraction vent stream. Further, the invention relates to a process for the recovery of aliphatic hydrocarbons from plastics comprising the above-mentioned process; and to a process for steam cracking a hydrocarbon feed comprising aliphatic hydrocarbons as recovered in one of the above-mentioned processes.

Abstract: The invention relates to a process for the recovery of aliphatic hydrocarbons from a liquid stream comprising aliphatic hydrocarbons, heteroatom containing organic compounds and optionally aromatic hydrocarbons, involving a) liquid-liquid extraction of said liquid stream with an extraction solvent thereby recovering part of the aliphatic hydrocarbons; b1) mixing the extract stream, comprising extraction solvent, aliphatic hydrocarbons, heteroatom containing organic compounds and optionally aromatic hydrocarbons, with a demixing solvent to recover additional aliphatic hydrocarbons; b2) mixing the remaining stream with additional demixing solvent to remove heteroatom containing organic compounds and optional aromatic hydrocarbons; and c) separation of the remaining stream into a demixing solvent stream and an extraction solvent stream. Further, the invention relates to a process for the recovery of aliphatic hydrocarbons from plastics comprising the above-mentioned process; and to a process for steam cracking a hydrocarbon feed
comprising aliphatic hydrocarbons as recovered in one of the above-mentioned processes.

Abstract: 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.
