System for processing interface emulsion, water and solids

A method for processing interface emulsion, water, and solids contained within a separator vessel 12 that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell 60. Providing discrete extraction points 30, 40, 44 for the inte...

Summary:A method for processing interface emulsion, water, and solids contained within a separator vessel 12 that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell 60. Providing discrete extraction points 30, 40, 44 for the interface emulsion, water, and solids, each of the extraction points being located within the vessel; setting a first removal rate for the interface emulsion and a second removal rate for the water and solids; and providing an induced gas flotation cell having an inlet 62 to which the interface emulsion, water, and solids are passed from their respective extraction points into the cell for treatment; discharging the oil from an oil outlet 66 located in an upper portion of the cell and treated water from a water outlet 70 located in a bottom portion of the cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of the method comprise a closed system with no air emissions.
