SUBSEA FLUID PROCESSING SYSTEM WITH INTERMEDIATE RE-CIRCULATION

摘要

A fluid processing system is provided containing a pump and a fluid reservoir. The pump includes a casing, one or more pump stages, a pump inlet, and a pump outlet. The casing includes one or more slots, with at least one slot configured to extract at least a portion of a multiphase fluid flowing within the pump. The fluid reservoir encompasses at least a portion of the casing and is configured to receive and separate the portion of the multiphase fluid into an extracted liquid phase and an extracted gaseous phase. The fluid reservoir includes a re-circulation conduit disposed proximate to the pump inlet and a discharge device coupled to the re-circulation conduit. The discharge device regulates re-circulation of at least a portion of the extracted liquid phase to the pump via the pump inlet for reducing a gas volume fraction of the multiphase fluid being fed to the pump.

1. A fluid processing system comprising:
a pump including a casing, one or more pump stages, a pump inlet, and a pump outlet, the casing defining one or more slots, wherein at least one of the slots is configured to extract at least a portion of a multiphase fluid flowing within the pump, wherein each pump stage comprises a diffuser and an impeller; and a fluid reservoir encompassing at least a portion of the casing and configured to receive and separate the portion of the multiphase fluid into an extracted liquid phase and an extracted gaseous phase, wherein the fluid reservoir comprises a re-circulation conduit disposed proximate to the pump inlet, and a discharge device coupled to the re-circulation conduit and configured to regulate re-circulation of at least a portion of the extracted liquid phase to the pump via the pump inlet so as to reduce a gas volume fraction (GVF) of the multiphase fluid being fed to the pump.
