SUBSEA FLOW ENHANCER
The present invention is for a subsea hydrocarbon recovery device comprising a means for separating a composite hydrocarbon stream into a gas and liquid stream and independent means for recovering each stream. The device is comprised of a separator (14), a gas recovery pipeline (20) and a liquid recovery system. The separator separates a composite hydrocarbon stream from a well (10) into vapor and liquid phases. The liquid hydrocarbon recovery system is comprised of a circulating loop (29) into which the liquid hydrocarbon stream is introduced for recovery. The liquid stream flows through a pressure increasing device (43) into a circulating loop (29) which brings the recovered hydrocarbon to the surface. Physical parameters of the circulating liquid can be controlled to prevent or eliminate paraffin accumulations.
