Abstract
An oil recovery system comprises a first separator preferably in the form of a three-stage "knock-out" tank (54) connected to receive crude oil from an oil-well (50). Water contaminated with oil is lead from the first separator to the inlet manifold (48) of a second separator bank (10) preferably consisting of one or more cyclone separators which separates the inlet mixture into separate water and oil components. The outlet pipe (35) for the separated water component selectively discharges to an outlet (82) or recycled through the cyclone separated; preferably in accordance with the degree of oil contamination of the separated water component.
