Abstract:
A Combined Electrolysis Catalytic Exchange (CECE) facility is running at the Tritium Laboratory Karlsruhe (TLK) in order to investigate the simultaneous transfer of tritium and deuterium between various molecular hydrogen isotopes in gas and water, employing a Liquid Phase Catalytic Exchange (LPCE) column. Currently a glass column with an active height of 2 m and a diameter of 58 mm is being used. Experiments are performed to determine the height equivalent of theoretical plate (HETP) and the mass transfer coefficients during simultaneous deuterium and tritium exchange between deuteriated and tritiated water and gaseous hydrogen isotopes. The experiments are aimed to provide the data required for the design of large isotopic exchange columns needed for the recovery of tritium from waste water generated during the operation of the tritium facilities of fusion machines. The exchange column is filled with a mixture of catalyst (platinum on charcoal and PTFE) and ordered packing layered in the column. Pre-heated water at the working temperature is fed into the column from the top and tritium-deuterium-hydrogen mixtures saturated with water vapour from the bottom. ... mehr
