Abstract
A process is provided for the treatment of suspensions comprised of oil, water and solids in which the suspension is subjected to centrifugation employing a centrifugal filter, coated with an organic powder having an index of compressibility comprised between 0 and 1.2, and wherein under the effect of the centrifugation, the suspension is subjected to an acceleration comprised between 10 and 2500 times the gravity force, that is, 100 to 25000 m/s.sup.2. The solids are retained by the coating and the centrifugate is collected. The invention is useful for the treatment of crude oil, of lubricants and oils which produce suspensions or emulsions rich in fats.
