  • System and method for multiphase pump lubrication
    Patent number: 8425667
    Abstract: A subsea system includes a multiphase pump, configured to transfer a multiphase fluid and a multiphase separator, configured to separate the multiphase fluid into solid, liquid, and gaseous phases. The multiphase separator includes a solid-liquid separation device, which is configured to facilitate separation of the solid phase and the liquid phase from the multiphase fluid. The multiphase separator includes a gas-liquid separation device, which is configured to facilitate separation of the gaseous phase and the liquid phase from the multiphase fluid. The multiphase separator includes a liquid reservoir, which is configured to contain a volume of the liquid phase to be used as a lubricant for the multiphase pump. Finally, the multiphase separator includes a liquid outlet, which is configured to transfer the liquid phase from the liquid reservoir to the multiphase pump.
