ABSTRACT:
An oil spill recovery method and apparatus is disclosed. The method of recovery involves the pumping of an oil/water mixture from a concentration area to the submerged portion of a vertically oriented cylinder, open at both ends, and the separation of the oil from the water in the cylinder. Oil floats to and accumulates on the surface of the water in the cylinder and uncontaminated water flows out through the lower open end of the cylinder. The apparatus includes a collection unit which defines the concentration area within three walls thereof, a recovery unit which follows the collection unit and mounts the cylinder therein, and a submerged pumping unit which carries an oil/water mixture from the concentration area in the collection unit to the cylinder in the recovery unit. There is very little emulsification of the oil in the cylinder and hence there is very efficient separation of the oil from the water.
