Fluid separating vessel

A fluid separating vessel (1) comprises: a liquid outlet (3) near the bottom of the vessel; a gaseous fluid outlet (4) near the top of the vessel; a plurality of cyclones (5) arranged in an upper region of the vessel in which at least some liquid droplets that may be entrained in the substantially gaseous fluid stream flowing in upward direction from a fluid inlet (2) towards the gaseous fluid outlet (4) are coalesced, separated from the gaseous carrier fluid and induced to drip down towards the liquid outlet (3) via a liquid return conduit (7); and a plurality of rotating liquid coalescing centrifuges (8) that are arranged below the cyclones (5), in which liquid coalescing centrifuges (8) fluid fed to the cyclones (5) is pre-treated such that at least some liquid droplets that may be entrained in the substantially gaseous fluid stream flowing in upward direction from the fluid inlet towards the cyclones are coalesced.
