Working Liquid Holdup by Irregular Fine Packing in Uranium Hexafluoride Rectification

Abstract

The rectification of uranium hexafluoride and its main technological impurities – tungsten and molybdenum hexafluorides – was studied. Irregular, fine, spiral, and spiral-prismatic packings were used as the separating elements. It is shown that the dependence of the working holdup of liquid metal-hexafluorides on the rectification parameters in a packing column with irregular fine packing is identical to the dependences given in the literature but with different coefficients and exponential factors.
