Title:
SEPARATION OF METHANOL, ETHANOL AND/OR DIMETHYL ETHER FROM HYDROCARBON MIXTURES
Document Type and Number:
WIPO Patent Application WO2005026087
Kind Code:
A8
Abstract:
The present invention is a separation process for producing a methanol, ethanol and/or dimethyl ether stream from a first stream containing C3+ hydrocarbons. The first stream comprises C3+ hydrocarbons, methanol, ethanol and/or dimethyl ether, The process comprises the step of passing the first stream through an adsorbent bed having a crystalline microporous material that preferentially adsorbs methanol, ethanol and/or dimethyl ether over the C3+ hydrocarbons.
