水電解工場における副産重水製造法の最適濃縮カスケード

電解・交換反応法＋水精溜法＋回収電解法

An analysis to get the most economical combination of three methods of heavy water enrichment, such as elctrolysis-exchange reaction, distillation and recovery electrolysis was made under the condition that the heavy water solution, by-product from a normal water electrolysis plant is available as a raw material.
As the result, the following combination was obtained as the optimum enrichment cascade in the case we are going to plan.
4 stages of electrolysis-exchange towers up to 3 wt% of D₂O
Distillation plant from 3 to 28.8 of D₂O

Recovery electrolysis plant from 28.8 to 99.8 of D₂O
