Abstract

In separating a liquid into two fractions by thermal diffusion in a column between two walls spaced uniformly apart at 0.01-0.15 inch and maintained at different temperatures, the liquid is introduced at one end of the column, a first fraction is continuously removed at the other end of the column, and a second fraction is continuously removed from the feed end, the ratio of rate of removal of the first fraction to the rate of feed being less than about 1.5:10 by volume. The feed is introduced at the top or bottom of the column adjacent one of the walls and the second fraction is withdrawn adjacent the other wall. The feed rate is preferably at least equal to the normal rate of thermal circulation. Four separation columns may be used in parallel, or two in parallel and the small portions combined and led to a third column from which the large portion is recycled with the main feed. Graphs show the effect on the degree of separation of the small fraction withdrawal rate, the feed rate, and the ratio between these rates. The separation of a petroleum lubricating oil is described and reference is also made to the concentration of stigmasterol from soy bean oil, and the separation of odorous substances from a fish oil.
