气体分离试验是在从宇部工业购买的小型聚酰亚胺膜组件上进行的，其中含有少量的氢或氚，类似于日本原子能研究所(JAERI)开发的组件。实验结果表明，该分离工艺有可能应用于氚处理设施中的氚去除系统。这将大大减少传统氧化-吸附工艺要处理的气体体积，从而减少相关设备的数量或规模。因此，处理因元素氚转化而产生的高毒性氚水蒸气所产生的危险将会降低。
Gas separation tests were performed with nitrogen containing small concentrations of deuterium or tritium on a small-scale polyimide membrane module purchased from Ube Industries, similar to that developed at the Japan Atomic Energy Research Institute (JAERI). Experimental results showed that this separation process could be potentially applied to tritium removal systems used in tritium handling facilities. It would allow to reduce significantly the gas volume to be treated by the conventional oxidation-adsorption process, and, therefore, the number or size of associated equipments. Hazards arising from handling of highly toxic tritiated water vapor due to conversion of elemental tritium, would hence be lowered.
