Abstract: There is described subsea apparatus and a method for processing fluid from a well. In an embodiment, a pipeline may be arranged to carry the multiphase fluid containing liquid and gas from the well. An outlet extending through a wall of the pipeline may let gas out of the pipeline from said region and through the outlet to separate said gas and liquid. A compressor may be connected to the outlet to compress the separated gas. Separated liquid may be conveyed along a sloping portion of the pipe to a low point in the seabed terrain, and may be conveyed to a pump for boosting the flow of liquid. The pump may be located in an excavated hole or glory hole below the seabed.

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.

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.
