METHOD OF SEPARATING OLEFINS FROM MIXTURES WITH PARAFFINS |
| 摘要 |
<p>A process for the separation or concentration of olefinic hydrocarbons from mixtures of olefinic and paraffinic hydrocarbons uses a polyimide membrane. The process is well suited to separating propylene from propylene/propane mixtures. The novel method The membrane exhibits good resistance to plasticization by hydrocarbon components in the gas mixture under practical industrial process conditions.</p> |
