ABSTRACT:
Apparatus for maintaining the level of an interface between separate phases in a solvent extraction column by regulating the flow from the base of the column. A steady controllable flow is achieved by passing the flow into a pressure vessel and the level in the vessel is controlled by having a plurality of vertically spaced apart apertures in the flow path within the vessel.
