| titleOfInvention | Method for treating a nuclear process off-gas stream |
| abstract | Method for selectively removing and recovering the noble gas and other gaseous components typically emitted during nuclear process operations. The method is adaptable and useful for treating dissolver off-gas effluents released during reprocessing of spent nuclear fuels whereby to permit radioactive contaminant recovery prior to releasing the remaining off-gases to the atmosphere. Briefly, the method sequentially comprises treating the off-gas stream to preliminarily remove NOx, hydrogen and carbon-containing organic compounds, and semivolatile fission product metal oxide components therefrom (11 and 16); adsorbing iodine components on silver-exchanged mordenite (17); removing water vapor carried by said stream by means of a molecular sieve (31); selectively removing the carbon dioxide components of said off gas stream by means of a molecular sieve (51); selectively removing xenon in gas phase by passing said stream through a molecular sieve (71) comprising silver-exchanged mordenite; selectively separating krypton from oxygen by means of a molecular sieve (91) comprising silver-exchanged mordenite; selectively separating krypton from the bulk nitrogen stream using a molecular sieve (111) comprising silver-exchanged mordenite cooled to about -140 to -160 C; concentrating the desorbed krypton upon a molecular sieve (131) comprising silver-exchange mordenite cooled to about -140 to -160 C; and further cryogenically concentrating, and then recovering for storage, the desorbed krypton (137). |
