同位素水精馏非稳态过程制备低氘水的研究与应用

Research and Application of Unstable State Behavior in Isotope Water Distillation Prepared Deuterium Depleted Water

根据水精馏过程中氢、氧稳定同位素的分离特性,以及同位素精馏的稳态和非稳态级联过程的理论分析和研究,应用于水精馏法生产重氧(18O)水的分离过程,在连续生产重氧(18O)水的同时,间歇副产低氘水,使一套同位素分离装置能同时制备二种同位素产品,开发了同位素水的综合制备的技术,提高了分离装置的有效利用率。

The resparation technology was developed on the basis of the study of characteristics of hydrogen and oxygen stable isotope in water distillation separation process and the analysis of steady and unsteady state behavior in the isotope distillation cascade process.While heavy oxygen（^（18）O） water is produced continuously,deuterium depleted water can be prepared batchuirse as by-product.Using this technology one set of isotope separation devices can simultaneously produce two kinds of isotope products,and the effective utilization of the separation devices is improved.
