Influence of the Degree of Distillation and Temperature on the Effective Separation Factor

Abstract

We demonstrate the feasibility of constructing the dependence of the effective separation factor β on the degree of distillation (g) and temperature (at known values of the vapor pressure of the substance being evaporated, the Peclet number at its melting point, the activation energy for impurity diffusion, and the initial separation factor β₀) via construction of the dependence of condensate purity on g at a given β₀ and Peclet numbers corresponding to a series of temperatures under consideration. We present calculation of such a dependence for a beryllium-based model material as an example and examine its typical features.
