PACKED ABSORPTION TOWERS

摘要

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 zo ne for distributing liquid onto the packing pieces; a gas feed inlet below the pack ing 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 pie ce size, disposed within a first region of the packing zone defining an annulus adjacent an up per part of the tower wall, and a second plurality of packing pieces of a second packing pie ce size greater than the first packing piece size, within a second region of the packing zon e. The packed tower provides higher efficiencies in gas absorption over prior art towers a s to offer reduced tower and/or packing heights.
