ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to settling tanks that separate emulsions.
BACKGROUND OF THE INVENTION
Settling tanks are used to separate emulsions into their constituents. Separation of the constituents can be achieved by skimming, heating, or chemical processes.
SUMMARY OF THE INVENTION
The present invention is an apparatus for separating oil from a water based emulsion with a known volumetric percentage of oil. The apparatus includes a tank structure configured to contain the emulsion. The tank structure defines a lower settling chamber with an opening at a terminal upper end. The tank structure further defines an upper settling chamber that communicates with the lower settling chamber through the opening. The opening allows the oil in the emulsion to rise from the lower settling chamber into the upper settling chamber, and thereby to form an oil layer that floats on the water at a level above the opening. The lower settling chamber has a first volume. The upper settling chamber has a second volume, including a partial volume above the opening. Importantly, the partial volume above the opening, as a percentage of the sum of the first and second volumes, is greater than the known volumetric percentage of oil in the emulsion.
