ABSTRACT:
A method and apparatus for removing oil or other hydrocarbons from the surface of a body of water by the distribution of discrete buoyant porous member upon the water surface, continuously removing the members from the surface, removing the absorbed oil from the members in a recovery assembly, and returning the members to the surface of the water for reuse. The members are rigid, porous spheres with oleophilic hydrophobic material herein. The recovery assembly includes a housing having a rotating frame therein with a wheel rotatably mounted thereon for carrying a plurality of members. A motor rotates the wheel and frame and a feed successively feeds members into the rotating wheel for centrifuging. A discharge removes the balls from the wheel after a set period of time and returns the balls to the surface of the water.
