A dynamic simulation of cryogenic hydrogen isotope adsorption in molecular sieve beds

摘要

As one of the most important systems in HCCB TBM of ITER, Tritium extraction system will collect hydrogen isotopes by cryogenic adsorptive method. Aspen Adsorption was adopted to simulate the process of a He-D-2-H-2 mixture (the mole fraction of He is 99.9%) adsorption in the molecular sieve bed. Furthermore, breakthrough curves of hydrogen isotopes in MSB will be applied to analyze the effect of pressure, flow rate and mole fraction on the MSB. The concentration distributions of hydrogen isotopes in the bed will bring another perspective for hydrogen adsorption in MSB. As a result, this simulation model can provide the theoretical basis of MSB engineering design in the future.
