<p><P>PROBLEM TO BE SOLVED: To improve refining purity of uranium hexafluoride before re-enrichment. <P>SOLUTION: The purity of refined object component is increased by a first condenser 3 cooling treating object gas 1 containing the object component gas to be refined and impurities to condense the object component gas, a second condenser 5 cooling the impurities and uncondensed object component gas discharged from the condenser 3 at a lower temperature than the condenser 3, a heating process heating the condensate of the object component condensed in the condenser 5, and by returning the gas gasified in the heating process to the condenser 3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
