ABSTRACT:
A reverse osmosis process is described for removing alcohols from hydrocarbons, in the additional presence of ethers. Depending on the nature of the membrane used, the methanol can be selectively removed as the membrane permeate or retained as the membrane concentrate. The membrane may be made from cellulose esters, polyethylene, polyvinylchloride, polyvinylidene chloride-polyvinyl chloride, etc.
