Apparatus and a method for gravity separating lighter and heavier liquids are disclosed, the apparatus including a vessel with its interior divided by a horizontal baffle into upper and lower spaces, which are in communication at one end. The horizontal baffle is shaped to provide a sloping floor in the upper space. Mixed lighter and heavier liquids are passed into the lower space, forming a heavier, lower phase, containing most of the heavier liquid and a lighter, upper phase containing the lighter liquid and a small amount of heavier liquid. The lighter phase passes into one end of the upper space. The opposite end of the upper space has a vertical baffle to retain the lighter phase above the sloping floor formed by the horizontal baffle. The minor portion of heavier liquid separates by gravity from the lighter phase and flows toward the lower portion of the sloping floor, and the lighter liquid is removed from the vessel through an outlet orifice located at the higher portion of the floor. The minor portion of heavier liquid is drained from the lower portion of the sloping floor into the heavier phase.

Apparatus for gravity separation of a lighter liquid from a heavier liquid comprising in combination: a vessel adapted to contain a mixture of said heavier and lighter liquids flowing longitudinally therein; generally horizontal baffle means extending transversely entirely across the interior of said vessel and extending longitudinally to separate an upper space above said baffle means from a lower space below said baffle means in said vessel, said upper space and said lower space being in communication through passage means located adjacent a first longitudinal end of said baffle means; said baffle means defining a sloping floor of said upper space, said floor having a higher portion and a lower portion; means extending upwardly from a second longitudinal end of said horizontal baffle means to a height above said higher floor portion and extending transversely entirely across said horizontal baffle means for preventing the flow of liquid between said upper space and lower space; said vessel including inlet means for introducing a mixture of said lighter liquid and said heavier liquid into said vessel and into said lower space adjacent said second longitudinal end of said baffle means, said mixture flowing toward said first end of said baffle means whereupon said heavier liquid gravity separates from said lighter liquid and collects along the bottom of said lower space, and said lighter liquid flows along the top of said lower space and enters said upper space through said passage means; said vessel including liquid outlet means communicating with said lower space for conducting said heavier liquid from said vessel; first conduit means communicating with said upper space for conducting said lighter liquid from said vessel; and second conduit means communicating with said upper space at a location lower than said first conduit means and adjacent said lower portion of said upper space floor for conducting from said upper space into said lower space heavier liquid which enters said upper space and gravity separates from said lighter liquid along said sloping floor. Apparatus as defined in claim 1 further including a generally vertically oriented coalescing pad disposed transversely within said vessel between said inlet means and said horizontal baffle means.
