ABSTRACT:
A system for treating oil-contaminated drill cuttings includes a grinder for increasing the surface area of the drill cuttings to enhance the absorption of free oil on the cuttings. A mixer enhances the absorption of free oil into the additional solid, oil-absorbent material exposed through the increased surface area of the ground cuttings. After mixing, the ground cuttings may be compacted into individual masses of sufficient density to sink in water. Fine materials are separated from said compacted masses prior to disposal in a marine environment.
