High pressure separation of dimethyl ether from an olefin stream |
| abstract |
Disclosed is a method of removing dimethyl ether from an ethylene and/or propylene containing stream. Dimethyl ether is removed at a high pressure, preferably in a distillation column. The high pressure separation has the benefit of providing a relatively low bottoms temperature separation, while allowing for recovery of a highly concentrated ethylene and/or propylene stream. |
