ABSTRACT:
An oil-and-water mixture is supplied to a tank which is closed at the bottom and open at the top, generally midway between top and bottom. A closed vessel envelops the upper portion of the tank. A vacuum is drawn at the top of the tank and vessel. An oil coalescer is placed between the mixture supply and the open tank top and a water coalescer between the supply and the closed tank bottom. Separated oil spills over the open tank top into the vessel, and is discharged from there. Separated water is discharged from the closed tank bottom.
