Produced water-oil separation tank for emulsions

U.S. Patent Number: 5340477

Abstract: A separator apparatus for breaking emulsions, particularly an emulsion formed of the hydrocarbon liquid and an aqueous solution, wherein the emulsion is introduced to a main separating tank. The latter includes at least one inlet for introducing emulsion, and a separate discharge port for conducting hydrocarbon-free aqueous component from the tank. An overflow trough positioned near the tank proportion includes a stripping weir which passes the flow of the hydrocarbon which has floated to the surface of the heavier water component. Emulsion flow to the tank is controlled by a flow regulator comprised primarily of a water level sensing means.
