Process for removing oxygenate from an olefin stream |
| 摘要 |
The present invention relates to a process for removing dimethylether from an olefin stream comprising dimethylether, comprising: (a) providing to an oxygenate recovery zone the olefin stream comprising dimethylether and a methanol-comprising solvent, treating the olefin stream comprising dimethylether with the methanol comprising solvent, and retrieving at least a dimethylether-depleted, methanol-comprising olefin stream; and (b) providing to the oxygenate recovery zone a non-aqueous C2 to C4 alcohol solvent and treating the dimethylether-depleted, methanol-comprising olefin stream with the non-aqueous C2 to C4 alcohol solvent, and retrieving from the oxygenate recovery zone at least an olefinic product that is depleted in dimethylether and methanol and a spent solvent comprising at least one C2 to C4 alcohol and methanol. |
