摘要：

According results of a theoretical analysis of the countercurrent column operation for the liquid phase catalytic exchange (LPCE) between hydrogen and water in a mode with independent flows of hydrogen and water, it is shown that there are temperature-dependent maximum values of the molar ratio of hydrogen and water flows, at which the separation performance of the column towards isotope mixtures of protium-tritium and protium-deuterium diminishes. Options for the operation of a chemical treatment column were experimentally studied provided that water vapor condensate is returned to the column from the output steam-gas flow or without it. The experimental results are consistent with the theoretical analysis performed.
