Subsea Multiphase Pump or Compressor with Magnetic Coupling and Cooling or Lubrication by Liquid or Gas Extracted from Process Fluid

摘要

A submersible fluid system for operating submersed in a body of water includes an electric machine and a fluid-end. The fluid-end includes a fluid-end housing having an inlet to a fluid rotor, the fluid rotor coupled to the electric machine and carried to rotate in the housing by a bearing in the housing. A fluid separator system receives a multiphase fluid and communicates a flow of the fluid to the inlet and a substantially liquid flow extracted from the multiphase fluid to the bearing.

1. A submersible fluid system for operating submersed in a body of water, the system comprising:
an electric machine; a fluid-end, comprising a fluid-end housing having an inlet to a fluid rotor, the fluid rotor coupled to the electric machine and carried to rotate in the housing by a bearing in the housing; and a fluid separator system that receives a multiphase fluid and dispenses flows of a multiphase fluid to the inlet and dispenses flows of a substantially liquid flow extracted from the multiphase fluid to the bearing.
