Abstract

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.

分析逆流色谱柱在水和氢独立流动的情况下进行氢与水化学同位素交换的运行模式
摘要根据对氢气和水之间液相催化交换(LPCE)的逆流塔操作进行理论分析的结果表明,氢气和水的摩尔比存在与温度相关的最大值,在该值上,塔对氕氚和氕氘同位素混合物的分离性能降低。通过实验研究了化学处理柱的运行方案,即从输出蒸汽气流中返回或不返回水蒸气冷凝液。实验结果与理论分析一致。
