... ABSTRACT As an important equipment in subsea booster system, helico-axial multiphase pump plays a significant role in subsea oil and gas development. In this study, the variations of condition parameters in each stage of a three-stage helico-axial pump was investigated by using a commercial...

... Abstract Twin-screw multiphase pumps have been a good alternative to substitute conventional pumping equipment (composed, e.g., by fluid separation, liquid pumping and gas compression facilities) for petroleum boosting due to the fact that it is able to "pump" mixtures of liquid and gas...

... recirculation variation suction flow multiphase pump Abstract This paper presents a model of the thermo-hydraulic behavior of twin screw multiphase pumps, including effects of gradual opening of the last chamber and fluid recirculation between suction and discharge of the pump and different working...

... ABSTRACT: The two-phase flow of paraffinic oil and dry air conveyed by a twinscrew multiphase pump (MPP) is examined experimentally up to very high gas void fractions. The rotational speed is varied at a constant pressure difference boosted by the MPP. As results, tomography pictures...

... in a multiphase pump has to be controlled for inlet gas volume flow fractions higher than 0.98 according to Mueller-Link (2003). For high gas volume fractions the assumption that the gaps between the screws and the housing are filled with pure liquid is not valid any more. Gas is entereing into the gaps as well...
