ABSTRACT:
A process for purification of a substantially non-aqueous, viscous, contaminated organic liquid, in particular tri-ethylene glycol, comprising heating the contaminated organic liquid to a temperature in the range of about 70.degree. C. to about 100.degree. C. and passing the contaminated organic liquid through a reverse osmosis membrane at a pressure in the range of about 400 psig to 650 psig. As a result of passing through the reverse osmosis membrane, a purified organic liquid is formed on one side of the membrane and a retentate with contaminants removed from the contaminated organic liquid is formed on the other side of the reverse osmosis membrane.
