Summary

MOLECULAR SIEVES HAVE THE ADVANTAGE OF ASDORBING BOTH WATER AND CO2 AT AMBIENT TEMPERATURE, AND ALSO ACETYLENE WHICH IS A DANGER IN AIR SEPARATION PLANTS. THESE SIEVES HAVE BEEN USED SUCCESSFULLY IN PLACE OF SILICAGEL ADSORBERS OPERATING AT DIFFERENT TEMPERATURES FOR H2 O AND CO2 SEPARATELY. PLANTS HAVE BEEN BUILT ALSO OPERATING WITH SHORT PULSED REGENERATION TIMES REQUIRING ONLY LIMITED AMOUNTS OF HEAT. FOR THIS METHOD THE ADSORBER VESSELS MUST BE DESIGNED TO INSULATE THE CHARGE FROM THE VESSEL, SO REDUCING THE THERMAL MASS THAT MUST CHANGE TEMPERATURE TO FULLY HEAT THE CHARGE. D.W.H.
