摘要：<p>Apparatus for physically separating a mixture of a first least dense liquid and a second modial density liquid, and a third most dense liquid has an upright container with a liquid inlet, a bottom outlet adjacent the bottom and having a flow control valve, a bottom float in the container but above the bottom outlet, a lower outlet above the bottom float and having a flow control valve, a lower float above the lower outlet and operatively connected to the lower control valve, a second float above the lower float, an upper outlet above the second float, and an upper float adjacent to or above the upper outlet, the bottom and lower and second floats are connected in parallel with the lower float being connected to the lower outlet valve, and the second and upper floats are connected in series to the upper outlet valve; and the bottom float connected to the bottom valve; the lower and second floats are fillable with and sink in the least dense liquid and rise in the medial density liquid, the bottom float is filled or ballasted to sink in the least and medial density liquids and to rise in the most dense liquid, the upper float is air filled and rises in all three liquids. A method of separating three liquids includes the steps of ballasting the bottom lower and seconnd floats, opening the lower outlet in response to raising the lower float, raising the second float and thereby energizing a normally de-energized upper float upon the second float rise and thereby opening an upper outlet for the least dense liquid the lower and second floats are ballasted to a specific gravity inbetween the specific gravities of the least and medial density liquids and the upper float is bouyant in the least dense liquid, the bottom float is raised by the most dense liquid and opens a bottom outlet for the most dense liquid; the method may be either pressurized or at atmospheric pressure.</p>
