A method for recovering isotopologues from a gas stream is provided with a wet scrubber column, which includes a liquid inlet, a liquid outlet, a gas inlet, a gas outlet, and a plurality of bubble cap trays. An initial gas stream is enriched with isotopologues, while an initial aqueous liquid is depleted of isotopologues. The initial gas stream is countercurrently contacting the initial aqueous solution through the bubble cap trays as the initial gas stream traverses from the gas inlet to the gas outlet and as the initial aqueous liquid traverses from the liquid inlet to the liquid outlet. A processed gas stream is then captured from the gas outlet and is depleted of isotopologues. Simultaneously, a processed aqueous liquid is captured from the liquid outlet and is enriched with isotopologues.

A liquid phase catalytic exchange column with a catalyst is configured to receive hydrogen gas. The system uses the catalyst to exchange the hydrogen gas with the tritiated source yielding HT gas and tritiated water. The system monitors tritium content of the tritiated water. When a predetermined tritium level is detected, the tritiated water is released. The system also includes a gaseous permeation system comprising a permeable barrier for the selective extraction of gases.

The present invention provides a method for enriching an oxygen isotope which enables the oxygen isotope to be enriched without requiring regular replenishment of large amounts of the nitric oxide raw material and with a small liquid NO hold-up volume, without reducing the separation efficiency for the oxygen isotope. By performing a chemical exchange between a water acquired by adding hydrogen to an oxygen having a crudely enriched oxygen isotope produced by a first distillation device, and a nitric oxide discharged from a second distillation device, a nitric oxide having an enriched concentration of the oxygen isotope and a water having a reduced concentration of the oxygen isotope are obtained, and the nitric oxide is supplied to the second distillation device, while an oxygen obtained by electrolysis of the water having a reduced concentration of the oxygen isotope is returned to the first distillation device.
