Abstract

See full text

A cyclone separator for separating a fluid into a gas phase and a liquid phase. The cyclone separator includes a vertically oriented vessel with a gas phase outlet at an upper end of the vessel and a liquid phase outlet at a lower end of the vessel; at least one tangentially oriented fluid inlet at the upper end below the gas phase outlet of the vessel; a liquid extractor extracting liquid through the liquid phase outlet at a rate which forms a bulk liquid phase at the lower end of the vessel; and a gas extractor extracting gas through the gas phase outlet. The cyclone separator has at least one flow velocity deflector located at a level in proximity to the bulk liquid-gas interphase which changes the vertical velocity component of a liquid film travelling down the internal wall of the vessel to a horizontally oriented velocity component.
