Calculation of breakthrough curve of multicomponent hydrogen isotopes using cryosorption column

The effective tritium system should be designed to recover tritium from DT reactor blanket sweep gas in a form that is easy to transfer to the main fuel cycle. The cryosorption method using a porous adsorbent at the temperature of liquid nitrogen is one of the candidate processes for extracting tritium from the sweep gas. For designing of a cryosorption column for recovery of tritium from hydrogen-swamped helium sweep gas, it is necessary to predict the breakthrough curve for mixture of multicomponent hydrogen isotopes in helium. In this report, a method to calculate the breakthrough curve at cryosorption of multicomponent hydrogen isotopes on molecular sieve 5A, molecular sieve 4A or activated carbon at 77.4 K is presented.
