摘要： 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.

摘要： The invention relates to a process wherein a dialkyl carbonate stream containing an ether alkanol impurity is subjected to extractive distillation using an extraction solvent to obtain a top stream comprising dialkyl carbonate and a bottom stream comprising the extraction solvent and the ether alkanol impurity, wherein the extraction solvent is an organic compound containing one or more hydroxyl groups and one or more ester moieties and/or ether moieties. Further, the invention relates to a process for making a diaryl carbonate, comprising reacting an aryl alcohol with a stream containing a dialkyl carbonate from which stream an ether alkanol impurity has been removed in accordance with the above-described process.

摘要： A method for separating monoethylene glycol (MEG) from one or more oxygenates. The method includes providing a stream comprising MEG and one or more oxygenates to a distillation column, providing a water feed stream to a bottom of the distillation column, and removing a recovery stream comprising MEG from the distillation column. The distillation column is operated at higher temperatures than the thermal stability of MEG and the one or more oxygenates.
