A primary molecular sieve drying bed is regenerated by circulating a hot inert gas through the heated primary bed to desorb water held on the bed. The inert gas plus water vapor is then cooled and passed through an auxiliary molecular sieve bed which adsorbs the water originally desorbed from the primary bed. The main advantage of the regeneration technique is that the partial pressure of water can be reduced to the 10-9 atm. range. This is significant in certain CTR applications where tritiated water (T/sub 2/O, HTO) must be collected and kept at very low partial pressure.
