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.
