Abstract
A system for compressing a multi-phase fluid made up of at least one gaseous phase and at least one liquid phase, the system having at least one pair of pumping elements. The system includes an axial-flow pump P1 and a centrifugal pump P2 arranged after the axial-flow pump P1. The two elements are linked by an element which adjusts the fluid from the axial-flow pump to optimize the effect of the centrifugal pump.
