On the optimum cascade of manufacturing of heavy water as a by-product in the water-electrolysis plant. Electrolysis-exchange reaction+water rectification+recovery electrolysis

An analysis to get the most economical combination of three methods of heavy water enrichment, such as electrolysis-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.
