简介 PROBLEM TO BE SOLVED : To improve the refining purity of uranium hexafluoride before re-enrichment.SOLUTION : The purity of a refined objective component is improved by an adsorption process of adsorbing impurity by feeding the objective component gas to be refined and treated gas containing impurity through an adsorption tower 12 with which an adsorbent for adsorbing the impurity is filled, a condensation process of condensing the objective component by cooling the gas passing the adsorption process, and returning of the impurity discharged from the condensation process and un-condensed objective component gas to the adsorption process.
