The current state-of-the art for carbon dioxide removal from submarine atmospheres is the liquid amine absorption tower. Although efficient, there have always been concerns over the release of potentially toxic amines into the air. In recent years there has been a drive towards replacement technologies that utilise less volatile and toxic absorbents. QinetiQ, in collaboration with Nano-Porous Solutions Ltd (n-psl), have evaluated adsorbent media tube technology for carbon dioxide removal on-board submarines. n-psl’s Adsorbent Media Tube (AMT), in which the adsorbent is bound within the walls of the media tubes, provides a number of advantages over traditional packed beds of extruded molecular sieve, including faster adsorption kinetics and lower pressure drop. AMT also have a conductive carbon coating that allows for the highly efficient, focused thermal regeneration of the adsorbents. QinetiQ have evaluated an AMT module containing zeolite 5A molecular sieve. Results presented here show that the module is capable of adsorbing carbon dioxide under a range of concentrations typically found on-board an operational submarine. Vacuum desorption of the carbon dioxide from the AMT is also shown to be a practical regeneration method.
