The influencing factors on CECE’s separation of hydrogen isotopes were comprehensively investigated with a theoretical model.The separation factor of electrolysis cell αele has a remarkable influence on stripping efficiency and enrichment
and it is an effective way to improve enrichment by decreasing holdup of electrolysis cell.The separation performance at feeding point 1.5 m is better than that of 3 m
stripping efficiency and enrichment has a linear relationship with mass transfer coefficient in the range 3~4 mol·m-3·s-1.For all influencing factors
HD/H2O and HT/H2O have similar tendency
and HT/H2O has better separation performance than HD/H2O for the inherent thermodynamic difference of the two systems.
