Abstract
A water stream is treated to remove oxygen before injecting the water into an underground hydrocarbon reservoir. The water-oxygen mixture is separated by centrifugal action using fixed spin blades (). Oxygen is removed from the center of the conduit through a gas pipe () coupled to a vacuum pump (). Nitrogen may be introduced upstream of the centrifuge to dilute the water-gas solution to improve the efficiency of the gas-liquid separation.
