900033 000 A method for removing and recovering hydrocarbons contained in hydrocarbon/water mixtures. Hydrocarbons are stripped from nonflowing hydrocarbon/water mixtures in a tank by bubbles of inert gas, such as air, introduced under pressure. The air and hydrocarbons are vented from the tank and the water is removed from the tank when satisfactorily purified. The material in the tank preferably is heated. A two-tank process may be used wherein the second tank is filled while the stripping process in the first tank is taking place. The rate of flow of the inert gas is maintained at a low enough rate to allow recovery of product. RH
