| titleOfInvention | Method with extraction distillation column separation oxyalkylene |
| abstract | It relates to thick propylene oxide stream, such as from the intermediate flow of PO/TBA process, the method for separating propylene oxide.Thick propylene oxide stream can be made to pass through extraction distillation column.Distillation column uses C 8 ‑C 20 Alkane, as extractant, with overhead washing drum, operates at a temperature of the pressure more than 25 50psig and/or 70 150 DEG C.Thick propylene oxide stream includes 0.001 0.1% weight percent methanol always formed based on thick propylene oxide stream.Described system, method and apparatus can produce the propylene oxide stream than prior art with less formaldehyde and acetaldehyde. |
