  • Low pressure separation of dimethyl ether from an olefin stream
    Publication number: 20030199721
    Abstract: 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.
