A fluid is mixed into a mixture that has been separated from an oil well stream and comprises water, oil, and gas. The mixture comprising the fluid is led into a separator (3) and allowed to separate into a water phase and an oil/fluid phase. The cleaned water phase is removed from said separator (3) via an outlet for water. The oil/fluid phase is subjected to a separation step separating the oil/fluid phase into an oil phase and a gaseous phase from which gaseous phase the fluid is recovered by a condensation step and recycled for injection into the mixture. The separator is a liquid-liquid/gas separator (3) in which the pressure is in the range of 0.5 bar to 25 bar while the mixture comprising said fluid is separated into said water phase and an oil/gas phase. |
