Abstract: A process and apparatus for the continuous contact and the subsequent separation from one another of immiscible fluids differing in density from one another, in which the entrainment of either fluid by the other is suppressed by obliging the less dense fluid to flow radially inward, from an annular passage between the interlapped walls of two coaxial conduits, through a generally continuous spinning ring of the denser fluid connecting the overlapped outlet of the inner conduit with the overlapping wall of the outer conduit, the two immiscible fluids separating centrifugally from one another with the less dense fluid being withdrawn from an inner space closer to the axis of spin than the surrounding denser fluid being separately withdrawn from the outer conduit.
