ABSTRACT Apparatus and methods for physically separating a heterogeneous mixture of immiscible liquids utilizing the difference in the viscosities of the components. At least one moveable surface is enclosed by at least one stationary surface to form a processing passage. Viscous-drag-induced momentum is transferred preferentially from the moving surface(s) to the more viscous component of the mixture, moving it downstream toward a collecting and pressurizing obstructing member. The resulting pressure "squeezes" the less viscous droplets upstream to separate from the collected material and drain from the passage through a drainage opening. In a preferred embodiment, an annular channel rotates within a housing, dragging the mixture from an inlet to an obstructing member extending into the passage near an outlet. The separated less viscous component drains from a drainage opening in the housing, while the more viscous component is discharged through the outlet. In another preferred embodiment, a plurality of annular passages is interconnected for series operation by material transfer grooves formed in the closure surface of the housing.
