  • Subsea multiphase pumping systems
    Patent number: 7569097
    Abstract: In subsea multiphase pumping systems, the use of a gas-liquid cylindrical cyclone (GLCC) as a separator to recirculate liquid from pump discharge to pump suction, especially during high gas inlet conditions from a multiphase petroleum stream. Further contemplated is protection of the pump from momentary high gas inlet conditions due to an incoming slug flow profile from a petroleum stream, via transforming a naturally varying multiphase petroleum stream into separated phases for measured distribution to the pump suction and ensuring a minimum liquid flow.
    Type: Grant
    Filed: May 26, 2006
    Date of Patent: August 4, 2009
    Assignee: Curtiss-Wright Electro-Mechanical Corporation
