  • Drill cutting disposal system
    Patent number: 4595422
    Abstract: An apparatus for removing fluids and hydrocarbons in oil well drill cuttings and an apparatus adapted to cooperate with conventional rig shakers for removing a major portion of fluid in the cuttings solids. A major portion of the fluids is removed by shaking the fluids-solids mixture. The solids are agitated by a chemical solution facilitating chemical removal of hydrocarbons in the solids. The solids are placed in an apparatus which shakes the solids at a higher speed than the first shaking, further separating fluids from solids. Fine particles of solids are removed from centrifuging. The separated solids are then discharged from the apparatus for disposal.
