The effect of column number N, as well as the column height h of thermal diffusion columns, on the deuterium removal rate from water-isotope mixture in the countercurrent-flow Frazier scheme with total sum of column heights L (= Nh) fixed, has been investigated. The equations, which may be employed to predict the optimal numbers of column for the maximum performances, have been derived. Considerable improvement in deuterium removal rate is obtainable if the scheme is constructed with the optimal number of thermal diffusion columns, especially for large flow rate and smaller L.
