Abstract
A method for on line recovery of oil from an oil in water emulsion spilled in water includes the steps of: obtaining a stream of recovered material including an oil in water emulsion and water; inducing a gas into the stream and applying shear so as to provide a mixture wherein oil from the oil in water emulsion is adhered to bubbles of the gas; passing the mixture to a flotation compartment for allowing the oil adhered to the bubbles to rise to a surface of the mixture; and removing the oil from the surface of the mixture.
