Method of removing tritium

Purpose: To remove trituim in airs simply and reliably in a large amount. Constitution: Tritium contained in air is oxidized in an oxidizing column into water and incorporated in the air. The water-air mixture is caused to flow into and cooled in a first freezing type air drier where almost of tritium water in the air are condensated and separated from the air and, after falling through the drier, recovered by way of a drain tube. The air passing through the freezing type air drier in humidified by a humidifier and then caused to flow into the second freezing drier. Then, a slight amount of tritium water remained in the air is mixed with steams by the humidifier for easier separation, dried in a drier and removed with tritium into cleaned air. After properly humidifying the air in the humidifier, it is flown out through the exit. (Kamimura, M.)
