Abstract

A combined multi-phase pump and compressor unit and a gas compression system are provided. The combined multi-phase pump and compressor unit functions on a centrifugal principle for transporting liquid and gas from a flow conditioner to a remote multi-phase receiving plant, wherein a rotating separator separates liquid and gas upstream of a compressor part of the combined multi-phase pump and compressor unit, wherein the separated liquid is collected in a rotating annulus in such a way that the liquid is given kinetic energy which is converted to pressure energy in a static system, and wherein the pressurized liquid bypasses the compressor part of the combined multi-phase pump and compressor unit, and then is re-mixed with the gas downstream of the combined multi-phase pump and compressor unit.
