APPARATUS AND METHOD FOR GRAVITATIONAL SEPARATION OF THE PHASES OF A TWO PHASE LIQUID

13. A method for the gravitational separation of the first and second liquid phases of a two phase liquid containing predominantly a continuous first liquid phase with a dispersed second liquid phase, the second liquid having a lower specific gravity than the first liquid, the method comprising the steps of:providing a tank defining an interior chamber with an upper portion and a lower portion;
introducing the two phase liquid into the lower portion of the chamber by a feed inlet;
directing the two phase liquid generally upwardly from the feed inlet through an upward flow zone in the upper portion of the chamber such that the second liquid rises more than the first liquid and separates therefrom due to the difference between their specific gravities, and forms a floating layer above the remaining liquid with an interface therebetween;
directing separated second liquid from the floating layer to a second liquid outlet that is located in the upper portion of the chamber below the interface between the floating layer and the remaining liquid via a conduit having a barrier that permits the second liquid to flow to the second liquid outlet only when the top of the floating layer reaches a predetermined height;
while concurrently directing separated first liquid downwardly through channels defined by an array of baffles contiguous to the upward flow zone, and further through passages isolated from the chamber that communicate with the channels and carry separated first liquid to a first liquid outlet located in the lower portion of the chamber;
and concurrently determining the height of the interface between the floating layer and the remaining liquid with a sensor system, the sensor system being active to control a valve that adjusts the flow of separated first liquid through the first liquid outlet such that the height of the floating layer can be held constant.
