Abstract

As a result of a theoretical analysis of the operation of a countercurrent column of chemical isotope exchange (CIE) of hydrogen with water in the mode with independent ows of hydrogen and water, it has been shown that there are temperature-dependent maximum values of the molar ratio of hydrogen and water ows at which the separating power of the column with respect to isotope mixtures protium-tritium and protium-deuterium are signi cantly reduced. Variants of the operation of the CIE column were experimentally studied under the condition that the condensate of water vapor is returned to the column from the outgoing steam-gas stream or without it. The results of the experiments agree with the theoretical analysis carried out.
