摘要 |
K 9735 PROCESS FOR THE SEPARATION OF SOLVENTS FROM HYDRDCARBONS DISSOLVED IN SAID SOLVENTS A process for the separation of solvents from hydrocarbons dissolved in said solvents by contacting a feed solution (e.g. obtained from a dewaxing unit) comprising hydrocarbons dissolved in an aromatic solvent and a polar aliphatic solvent (e.g. toluene and methyl ethyl ketone) at elevated pressure with one side of a dense membrane which is substantially impermeable to said hydrocarbons and which membrane comprises a layer of a halogen-substituted silicone compound comprising units according to the general formula: wherein R1 and R2 represent moieties chosen from the group consisting of hydrogen, halogen, alkyl, aryl, aralkyl and halogen-substituted alkyl, aryl and aralkyl moieties, and recovering said solvents from the other side of the membrane.
