Apparatus and method for removing and recovering oil and/or other oil-based drilling mud additives from drill cuttings

摘要: Method and apparatus for removing oil-based drilling mud from drill cuttings in order to prepare the an environmentally safe disposal sea. A solvent range of solvents which may be condensed by ambient seawater vaporized heat internal combustion engine coolant is utilized process. The method this invention includes steps transporting mud-laden a solid feed tank (10) wherein are subjected turbulent mixing leave surface substantially free oil. then transported countercurrent flow column (20) countercurrent, laminar separate oily fines smaller than chosen diameter heavier solids. solids cleaned any remaining muds, separated cleaning ultimately returned sea environment. include further step treating laden separation return continuous process recycling recovered into system.
