Abstract: The invention provides a process for removing carbon dioxide from a gas stream comprising the steps of: (a) contacting the gas stream with an absorption solvent to obtain a gas stream with a reduced carbon dioxide content and a carbon dioxide-containing absorption solvent; (b) withdrawing at least part of the gas stream with the reduced carbon dioxide content; (c) withdrawing at least part of the carbon dioxide-containing absorption solvent obtained in step (a) and heat it to obtain a mixture comprising a gas phase, an aqueous liquid phase and a non-aqueous liquid phase, wherein carbon dioxide is predominantly present in the gas phase; (d) introducing at least part of the mixture obtained in step (c) into a gas lift reactor to further release carbon dioxide absorbed in the aqueous liquid phase and the non aqueous liquid phase, whereby the gas phase establishes circulation and mixing of the aqueous liquid phase and the non-aqueous liquid phase between a lower section of the gas lift reactor and an upper sectio

Abstract: A separation tray, suitable for mounting in a vertical column, for separating liquid/gas mixtures. The separation tray has horizontal upper and lower walls and a plurality of primary separation devices for separating a fluid into a primary gas and a liquid-enriched secondary gas. The invention is characterized by a secondary separation zone located in the inner free space between the upper and lower walls and the primary separation devices. Liquid-enriched secondary gas is removed through outlets in the primary separation devices and guided downwardly by return skirts into the inner free space, whereupon the entrained liquid in the liquid-enriched secondary gas is substantially removed from the secondary gas.
