Estimation of deuterium recovery from H–D gas mixture by thermal diffusion

The recovery of deuterium from hydrogen isotope mixture in continuous-type cryogenic-wall thermal diffusion columns was calculated by the modeling prediction modified from the previous studies. The transport coefficients in the correlation equation were determined with the use of the experimental results obtained by Arita et al., and along the method performed in the previous works. The relation between the separation factor and degree of separation is delineated. The experimental results conform well to the predictions.
