ABSTRACT OF THE DISCLOSURE System for recovering oil products from oil sands in which super- heated steam from a nuclear reactor is mixed with water in a chamber under high superatmospheric pressure to obtain hot water at a temperature near the boiling point at the prevailing pressure. The hot water enters a reaction tube which has an input extruder for feeding oil sands into the reaction tube in contact with the hot water to effect release of the oil from the sands. The outlet of the reaction tube opens into a hydrocyclone into which the reaction products of oil and sand and water are discharged. An extruder at the bottom of the hydrocyclone discharges separated sand and some water which passes into a settling tank to settle the sand and the clarified water filtered and returned to the pressure chamber. The separated oil together with some water from the hydrocyclone flows to an oil separator where the oil separates from the water, which latter is also returned to the pressure chamber. The oil may be separated into fractions in a fractionating column and the column bottoms may be hydrogenated and returned to the fractionating column. Better oil recovery from the oil sand can be achieved and more efficient operation attained.
