Abstract

Conventional distillation methods face significant challenges in xenon isotope separation. This paper proposes a cascaded distillation system based on a microchannel distillation （MCD） apparatus for

136

Xe enrichment. The relative volatilities， saturation vapor pressures， and enthalpies of vaporization of the nine Xe isotopes were determined， and a corresponding pseudo-component model was validated in Aspen Hyprotech Systems （HYSYS）. A ternary model was then used to optimize

the MCD parameters， identifying the optimal operating pressure， reflux ratio， and feed-to-product ratio effects on enrichment efficiency and reboiler power consumption. Subsequent optimization via uniform design， stepwise quadratic regression， non-dominated sorting genetic algorithm （NSGA）-III， and the technique for order preference by similarity to an ideal solution （TOPSIS） reduced power consumption while increasing

136

Xe abundance from 8.670% to 13.347%. This microchannel cascaded distillation system overcomes conventional limitations and offers a novel and efficient approach for

136

Xe enrichment with significant theoretical and practical implications.
