<p>An apparatus and method for centrifugally separating a mixture of liquids comprises a central inlet shaft (12), a surrounding rotor (14), and a housing shell (16). 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 (54), discharges the lighter liquid into the housing through a channel (61) through the weir and wall (36) of the separation chamber, and discharges the heavier liquid into the housing over a second weir (60). The inlet shaft may be built up to provide for efficient sheer 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.</p> |
