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; b) mixing the extract stream, comprising extraction solvent, heteroatom containing organic compounds and optionally aromatic hydrocarbons, with a demixing solvent to remove part of the 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, wherein before and/or after step c) additional heteroatom containing organic compounds and optional aromatic hydrocarbons are removed from that remaining stream and/or from a stream resulting from step c), respectively, by contacting the latter stream (s) with a sorption agent. 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 provides a process for recovering a metallic component from a process stream, said process comprising passing said process stream over a ceramic membrane comprising a selective layer with a pore size in the range of from at least 0.5 nm to at most 10 nm; applying a pressure difference across said ceramic membrane such that the pressure outside the ceramic membrane is at least 50 kPa lower than the pressure inside the ceramic membrane; and, thus, providing a permeate stream which has passed through the ceramic membrane and which is depleted in the metallic component and a retentate stream enriched in the metallic component; wherein the process stream is derived from a process for the conversion of saccharide-containing feedstock into glycols.
