Pressure Build-Up and Pulsations in Twin-Screw Multiphase Pumps Conveying Oil and Gas

The performance of twin-screw multiphase pumps is well-known for common mixtures of water and air. When conveying other fluids, their physical properties have to be taken into account as they gain influence on the conveying characteristic. The pressure build-up within the pump changes depending on the solubility of gas in oil. Although twin-screw pumps are known as continuous conveyors, pressure pulsations emerge in the outlet of the pump.
