    Sidestream Effect on Separation of H2/HD/D2 by Cryogenic Distillation

    • A computational model was constructed to study the separation of hydrogen isotopes by cryogenic distillation with sidestream feedback and a computational analysis was made for H2/HD/D2 system. The results show a remarkable influence of sidestream feedback on separation performance. D2 is dominant in reboiler and deuterium abundance may reach 0.90 with sidestream feedback while HD is dominant in reboiler and deuterium abundance can not exceed 0.50 without sidestream feedback. A peak of transformation of HD to D2 appears after about 40 h with sidestream while enrichment of HD is saturated without sidestream at the same time. The efficiency of deuterium stripping is best when a sidestream ratio is 1.
