Abstract
Apparatus for physically separating a mixture of a first less dense liquid and a second more dense liquid has an upright container with a liquid inlet, a lower outlet adjacent the bottom and having a flow control valve, a lower float in the container but above the lower outlet, a second float above the lower float, an upper outlet above the second float, and an upper float above the upper outlet; the 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; the lower and second floats are fillable and sink in the less dense liquid and rise in the more dense liquid, the upper float is air filled and rises in either liquid. A method of separating the two liquids includes the steps of ballasting the lower and second floats, opening the lower outlet in response to raising the lower float, raising the second float and thereby energizing a normally de-energizing upper float upon the second float rise and thereby opening an upper outlet for the less dense liquid, the lower and second floats are ballasted to a specific gravity inbetween the specific gravities of the less and more dense liquids and the upper float is bouyant in the less dense liquid.
