O separation and dehydration characteristics of Y-type zeolite adsorbentIwai, Yasunori; Uzawa, Masayuki*; Yamanishi, Toshihiko
Adsorber has been studied to apply in the first stage of water detritiation system processing more than 100 kg/h of high-level tritiated water generated in a future fusion plant. Zeolite is a suitable adsorbent since it is an inorganic matter having a large water capacity. Rapid dehydration characteristic as well as large HTO/HO separation factor is necessary for adsorber to minimize its size. Present experiments were focused on the effect of cation on HTO/HO separation and dehydration characteristics of Y-type zeolites. It was found that the isotope separation factors are around 1.1-1.2 under static conditions. As for dehydration, operating temperature fixs the movable water capacity of the zeolites and the capacity at room temperature is NaY 
CaY KY. HTO dehydration characteristics depend on the accumulated purge gas amount and the purge gas rate is less influential. It is found that pressure swing is an effective method for HTO dehydration.
