LOW PRESSURE SEPARATION OF DIMETHYL ETHER FROM AN OLEFIN STREAM |
摘要 |
Disclosed is a method of removing dimethyl ether from an ethylene and/or propylene containing stream. Dimethyl ether is removed at a low pressure preferably in a distillation column. The low pressure separation has the benefit of providing a relatively low temperature separation, while allowing for recovery of a highly concentrated ethylene and/or propylene stream. |
