Abstract: Disclosed is a compact liquid-liquid separation device useful for the separation of oil and water in hydrocarbon production operations, as well as systems and methods for use thereof. The device includes a separator body of generally vertical pipe having an upper portion and a lower portion, and an inlet to the separator body of generally horizontal pipe in fluid communication with the separator body and attached to the separator body between the upper section and the lower section. The inlet has a round cross-section portion and a reducing area nozzle portion in which the horizontal width of the inlet decreases symmetrically with proximity to the separator body. The vertical interface between the inlet and the separator body has a generally rectangular cross-section.

Abstract: A water separation system and method for treating multiphase hydrocarbon production streams is disclosed. The system may be employed to separate gas from the production stream, and then separate the liquid stream into its oil component and water component. A gas/liquid separator may be employed to separate a multiphase hydrocarbon production stream into a gas stream and a liquid stream. A liquid cyclone separator, positioned downstream from the gas/liquid separator, may be employed to divide the liquid stream into an oil dominated portion and a water dominated portion. The system may be used on land or on offshore platforms in locations where it is desirable to separate oil and water from hydrocarbon streams.
