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.

Abstract: A method of identifying the phase composition and/or changes in the phase composition of a fluid flowing through a turbomachine includes monitoring changes in at least one electrical parameter associated with operation of the turbomachine, and employing a known correlation between phase composition and or phase composition changes, and changes in the electrical parameter(s) to associate the monitored changes with changes in the actual phase composition of the fluid.

Abstract: A gas compression system and a method of flow conditioning by a gas compression system are provided. A gas compression system includes a compact flow conditioner in a form of a flow conditioner tank and a combined multi-phase pump and compressor unit comprising an impeller configured to compress a mixture of gas and liquid, wherein the gas compression system is configured such that the gas and the liquid are separated in the flow conditioner tank, the separated gas and liquid are sucked up through the separate gas and liquid pipes and re-mixed again upstream of the impeller, and the liquid is distributed in a gas flow by Venturi effect, and wherein the Venturi effect is obtained by a constriction in the outlet pipe to the impeller, just upstream of the impeller.
