OSTI ID:6252968

This patent describes an apparatus for separating a first liquid from a second liquid of lower specific gravity comprising: a vessel having inlet means for a mixture of the first and second liquids positioned above the liquid level in the vessel and including diffuser means for preventing turbulence in the vessel caused by air and high velocity liquid flow, the diffuser means comprising as inner pipe of holes, and an outer pipe of shorter length the the inner pipe and surrounding the inner pipe for intercepting the mixture passing through the holes and directing the mixture through opposite ends of the outer pipe; a generally vertical conduit in the vessel, the conduit having an inlet in the lower part of the vessel; a generally horizontal conduit sealingly coupled between the vertical conduit and a first opening in a wall of the vessel at a level above the inlet to the vertical conduit. The first opening provides a first outlet for the first liquid such that the first liquid reaches the first outlet only by passing through the inlet to the vertical conduit and such that the horizontal conduit establishes the level of the first liquid in the vessel; and a second outlet for the second liquid comprises a second opening in a wall of the vessel above the level of the first outlet.
