System for drying gas and use of the system

A system for drying gas, for example removing moisture (water) from natural gas in connection with the extraction of oil and gas, comprising a drying unit for drying the gas by means of a drying liquid that is circulated by means of one or more pumps (4) and mixed with the gas and a regeneration unit (C) that regenerates the drying liquid, wherein the drying unit comprises one or more processing stages (A, B), where each stage comprises a mass transfer unit in the form of a static mixer unit or pipe loop (2) in which the gas is mixed with the drying liquid and passed in the direction of flow of the drying liquid to a gas/liquid separator (3), and where the gas is designed to be passed on to the next stage (B) or on to an outlet (6), while the drying liquid is passed to the regeneration unit (C) and/or to the mass transfer unit (2) for the relevant processing stage(s) (A and/or B).
