Boron Isotope Separation Using Chemical Isotope Exchange with Thermal Flow Reversal

Abstract

The paper presents calculations of the process parameters of the chemical isotope exchange with a thermal flow reversal in the BF₃–C₆H₅OCH₃ system and engineering data for rectifying columns for its implementation. It is shown that the calculated parameters are in good agreement with those found the literature. The best engineering data are obtained for rectifying columns intended for the production of enriched (96 wt.% ¹⁰B enrichment) boron in the amount of 2 and 4 tons per year.
