Abstract
A hydrocarbon extractor, intended to be disposed above a tank (10) containing a mixture of a liquid and a liquid hydrocarbon, comprises a belt (16) made of an oleophilic material which is adapted to be immersed in the mixture and two oleophilic rollers (26, 28), disposed one on each side of the belt, for recovering the liquid hydrocarbon from the belt. The rollers are rotated in an opposite direction to that of the movement of the belt and at a higher speed than the belt to enhance the recovery process.
