<p>A generally vertical tube (10) communicates at its lower end with a reservoir (12) containing the heavier of two liquids to be separated. A vacuum system (16) is used to create a lower pressure at the top of the tube than at the bottom. A mixture of liquids to be separated is injected into the tube at an intermediate location (50) with relatively low velocity and turbulence below the level of the interface between the two liquids (58). The interface level is maintained by controlling the top-to-bottom pressure difference and the evacuation rate of the lighter liquid.</p> |
