Abstract
A method for separating liquids, particularly hydrocarbons from water, whereby a small amount of a high molecular weight polymer is dissolved in the hydrocarbon to render it viscoelastic. A hydrocarbon layer is then mechanically removed from the water in a manner which causes rapid stretching of the hydrocarbon with attendant development of elastic properties in the hydrocarbon layer. The polymer may be applied to the surface of the hydrocarbon as droplets of a relatively concentrated polymer solution or as solid particulates having a polymer core covered by a powdered solid material which is non-reactive toward the polymer.
