PISTONLESS SUBSEA PUMP

A method for boosting a multiphase fluid is provided. The method may include separating the multiphase fluid into a liquid phase and a gaseous phase in a separator, compressing the gaseous phase in a compressor, and discharging the compressed gaseous phase from the compressor to the discharge line....

Zusammenfassung:	A method for boosting a multiphase fluid is provided. The method may include separating the multiphase fluid into a liquid phase and a gaseous phase in a separator, compressing the gaseous phase in a compressor, and discharging the compressed gaseous phase from the compressor to the discharge line. The method may also include draining the liquid phase from the separator to a liquid reservoir, passively actuating an inlet control valve to flow the liquid phase from the liquid reservoir to a liquid tank, and actively actuating an inlet actuation valve to flow a motive gas from the compressor to the liquid tank to thereby pressurize the liquid phase contained therein. The method may further include passively actuating an outlet control valve to discharge the pressurized liquid phase from the liquid tank to the discharge line, and combining the compressed gaseous phase with the pressurized liquid phase in the discharge line.
