Abstract:
1. A method for improving the efficiency of gas removal in a vessel where a process liquid containing a gas is introduced into a vertical essentially cylindrical vessel tangentially along a wall of the vessel so that said liquid is brought into rotation and further removed at a bottom of said vessel, bringing, by means of centrifugal forces, the gas to be enriched in a portion of said liquid, redirecting this liquid portion having an enriched gas content to at least one vertical means arranged centrally in said vessel, and separately removing said redirected portion of said liquid, and said gas enriched portion of liquid is deviated into a central tube through at least one opening which is arranged within said tube or in connection therewith, and the liquid is redirected at an upper end of said tube, suitably by means of a buoyancy force of the enriched gas, by means of an ejector arrangement or by means of a vacuum arranged in said tube.
