ABSTRACT:
A floating liquid layer detection and recovery apparatus and process are disclosed for selectively siphoning and storing a floating or sinking liquid layer and more specifically to an apparatus for raising floating hydrocarbons on groundwater or surface water to a higher point in a semi-closed system without a pump or an outside energy source once the apparatus is in place. In conjunction with this apparatus an apparatus is provided to create a cone of depression without a pump or outside energy source. Thicker floating liquids are siphoned to a higher point to a tank where water is first occupied and are separated by specific gravity. The water, being heavier, completes the remaining segment of the siphon to a point at or below the point of origin. Thinner floating liquid layers are siphoned under the lower end of a downcomer tube by capillary action along a fibrous media where capillary action of the lighter liquid continues upward joining the first siphon flow directly to the tank. The apparatus preferably includes a floating member buoyant in water so that it may rise and fall with changes in the water level. The two siphoning processes float the floating liquid layer to a thickness at or less than a sheen. A third siphon may be incorporated from a recovery point or well to another point or well with a lower watertable to create a cone of depression.
