Abstract
An apparatus and method for centrifugally separating a mixture of liquids comprises a central inlet shaft, a surrounding rotor, and a housing shell. The mixture is injected into the rotor through the inlet shaft and the rotor separates the mixture in a radially sloped separation space containing a first weir, discharges the lighter liquid into the housing through a channel through the weir and wall of the separation chamber, and discharges the heavier liquid into the housing over a second weir. The inlet shaft may be built up to provide for efficient shear mixing and a sieve may be provided in the separation chamber. A two-stage separator may be constructed by providing a second separation chamber radially outward of the first after mixing of a separated liquid with a solvent and providing suitable discharge ports.
