Abstract
A system and method for extracting oil from a fluid mixture includes a separation vessel having an internal chamber that extends to a chamber elevation, an inlet port, a water outlet port, and an oil outlet port. A liquid storage tank has an inlet port, an upper outlet port located at an upper outlet elevation, and a lower outlet port. A first conduit system interconnects the separation vessel's water outlet port and the tank's inlet port and has a top conduit segment at the upper outlet elevation. A second conduit system interconnects the first conduit system and the tank's inlet port. The second conduit system intersects the first conduit system below the upper outlet elevation and above the chamber elevation. A pump may be employed to transfer fluid from the upper outlet port back to the separation vessel.
