The present work has the purpose to determine the flow behavior of both phases, gaseous and liquid, of the hydrogen isotopes in order to obtain a better separation factor between hydrogen and water, aD/T, in the D2-DTO large scale isotopic exchange column.
Seeing that direct determination of the fractions of the hydrogen isotopic species is difficult and rather imprecise, the numerical estimation method with high precision is strongly required.
Therefore we shall use series of isotope exchange process characteristic equations to obtain the precise results needed in the design process for the achievement of the operating data target.
A special attention will have the two first weight reactions in the isotopic exchange process:
D2(g) + DTO(v) ⇔ DT(g) + D2O(v)
DTO(l) + D2O(v) ⇔ DTO(v) + D2O(l)
