Isotope Purification of Gases Containing Deuterium and Tritium by the Method of the Phase Isotopic Exchange of Water

Abstract

The study of the method of the phase isotopic exchange (PIE) for the purification of gas flows containing deuterium and tritium is carried out. The experimental data obtained for a column with a diameter of 32 mm on a Sulzer copper oxidized packing showed that the mass transfer characteristics do not depend on the deuterium concentration. Based on these results, a mathematical model for separating three-isotope mixtures, which makes it possible to calculate the column parameters under different initial conditions, is developed.
