Abstract
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, a gas recovery pipeline and a liquid recovery system. The separator separates a composite hydrocarbon stream from a well into vapor and liquid phases. The liquid hydrocarbon recovery system is comprised of a circulating loop into which the liquid hydrocarbon stream is introduced for recovery. The liquid steam flows through a pressure increasing device into a circulating loop which brings the recovered hydrocarbon to the surface. Physical parameters of the circulating liquid can be controlled to prevent or eliminate paraffin accumulations.
