ABSTRACT:
An improved packed tower for effecting the absorption of a gas into a liquid, comprising a cylindrical tower wall defining a packing zone; a plurality of packing pieces contained within the packing zone; a liquid distributor above the packing zone for distributing liquid onto the packing pieces; a gas feed inlet below the packing pieces for feeding gas through the packing zone, the improvement wherein the plurality of packing pieces comprises a first plurality of packing pieces, of a first packing piece size, disposed within a first region of the packing zone defining an annulus adjacent at an upper part of the tower wall, and a second plurality of packing pieces of a second packing piece size greater than the first packing piece size, within a second region of the packing zone. The packed tower provides higher efficiencies in gas absorption over prior art towers as to offer reduced tower and/or packing heights.
