Abstract

A method and device for separating two liquid phases by means of a centrifuge. The position of the zone that separates them is varied by supplying additional heavy phase as a function of that position. Once the zone arrives at a certain location, traces of light phase will appear in the heavy-phase outlet. A shutoff is opened and additional heavy phase is supplied for a prescribed length of time through a separate intake, displacing the zone toward another location. The process is repeated, with more heavy phase being diverted through the heavy-phase outlet than is supplied through the product intake.
