Claim Text:
1. A method for separating a fluid into a gas phase and a liquid phase, the method comprising: employing a vertically oriented cyclone separator vessel having a gas-phase outlet arranged in an upper end of the vessel and a liquid phase outlet arranged at a lower end of the vessel; feeding the fluid, which is to be separated, into the vessel at a tangential flow direction at a height level below the gas phase outlet at a flow velocity sufficient to form a liquid film travelling down an internal wall of the cyclone separator vessel in a helical flow pattern; extracting liquid through the liquid phase outlet at a rate which forms a bulk liquid phase at a lower part of the cyclone separator vessel with a relatively constant height level of a bulk liquid-gas interphase; and extracting gas through the gas phase outlet, wherein at least one flow velocity deflector arranged adjacent to the internal wall of the cyclone separator vessel is employed at a level in proximity of the bulk liquid-gas interphase which changes a vertical velocity component of the liquid film travelling down the internal wall of the cyclone separator vessel to a horizontally oriented velocity component, wherein the at least one flow velocity deflector is arranged below the bulk liquid-gas interphase.
