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.

1. A gas compression system comprising: a compact flow conditioner in a form of a flow conditioner tank, configured to be placed below a sea level in close vicinity to a well head or on a dry installation, said flow conditioner tank being configured to receive a multi-phase flow of hydrocarbons through a supply pipe from a sub sea well for further transport of the hydrocarbons to a multi-phase receiving plant;a combined multi-phase pump and compressor unit comprising an impeller configured to compress a mixture of gas and liquid, the impeller functioning on a centrifugal principle such that the gas and the liquid are given increased pressure in the same combined multi-phase pump and compressor unit; andan outlet pipe connected to the flow conditioner tank at a first end and to the combined multi-phase pump and compressor unit at a second end, opposite to the first end, the outlet pipe being in a form of a constriction communicating with an upper, gas-filled part of the flow conditioner tank and a liquid pipe, the liquid pipe has a smaller diameter than the outlet pipe, the liquid pipe communicates with a lower, liquid-filled part of the flow conditioner tank and extends into the outlet pipe proximate to the impeller,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 the constriction in the outlet pipe to the impeller. 2. The gas compression system according to claim 1, wherein the flow conditioner tank is in a form of a horizontal cylinder having a larger diameter than a diameter of the supply line from the well, and having a longitudinal direction parallel to a fluid flow direction. 3. The gas compression system according to claim 1, wherein the combined pump and compressor unit comprises a rotating impeller. 4. The gas compressor system according to claim 1, wherein the flow conditioner tank is provided with an inherent cooler for reduction of dimensions and complexity of the gas compressor system for the fluid to exchange heat with surrounding sea water. 5. The gas compression system according to claim 1, wherein the flow conditioner tank comprises a second outlet pipe for removal of sand when required through a separate valve. 6. The gas compression system according to claim 1, wherein the flow conditioner tank is provided with at least one internally arranged flow influencing element, securing an even supply of liquid. 7. The gas compression system according to claim 1, wherein an arrangement of permanent magnets is utilized to collect magnetic particles from an extracted process flow stream from a process system, but not limited to the combined multiphase pump and compressor unit prior to feeding the processed gas to an electromotor and bearings. 8. The gas compressor system according to claim 1, further comprising a heating line into an anti-surge valve in order to prevent formation of hydrates by using hot cooling gas from motor cooling. 9. The gas compression system according to claim 8, further comprising a liquid removal unit configured to avoid recycling of liquid while utilizing an anti-surge line. 10. A method of flow conditioning by a gas compression system, the method comprising the steps of: receiving a multi-phase flow of hydrocarbons in a compact flow conditioner through a supply pipe from a sub sea well for further transport of the hydrocarbons to a multi-phase receiving plant, the flow conditioner being in a form of a flow conditioner tank below a sea level in close vicinity to a well head;separating, in the flow conditioner tank, liquid and gas from the multi-phase flow;sucking up the separated liquid and the gas via an outlet pipe connected to the flow conditioner tank at a first end and to an impeller at a second end, opposite the first end, the outlet pipe being in a form of a constriction communicating with an upper, gas-filled part of the flow conditioner tank and a liquid pipe, the liquid pipe has a smaller diameter than the outlet pipe and communicates with a lower, liquid-filled part of the flow conditioner tank and extends into the outlet pipe proximate to the impeller;re-mixing the liquid and the gas upstream of the impeller, wherein the liquid is distributed in a gas flow by Venturi effect where the Venturi effect is obtained by the constriction in the outlet pipe to the impeller;boosting by a combined multiphase pump and compressor unit the re-mixed gas and liquid as a mixture, wherein the combined multiphase pump and compressor unit comprises the impeller, which functions on a centrifugal principle such that within a same rotational movement, both, the gas and the liquid are given an increased pressure in the same combined multiphase pump and compressor unit; andtransporting the liquid and the gas from the combined multiphase pump and compressor unit to a remote multi-phase receiving plant.
