ABSTRACT:
A gas separator is configured to separate gas from a two-phase fluid. The gas separator includes a rotatable shaft, a plurality of separation stages and an outer housing. Each of the plurality of separation stages includes a rotor connected to the rotatable shaft, a diffuser downstream from the rotor and a crossover downstream from the diffuser. Each crossover is configured to remove gas from its respective separation stage. The outer housing includes a separate group of discharge ports for each separation stage to permit the removal of gas from each separation stage.
