Effect of diffusion on the purification of substances by distillation

Inorganic Materials Aims and scope

Abstract

This paper examines a mathematical diffusion model for the purification of substances by distillation. We present the dependences of the separation factor—a quantitative characteristic of the degree of purification of substances—and the effective separation coefficient on the Peclet number, vaporization rate, and sampling ratio. For selenium containing barium impurities, we determine the equilibrium separation coefficient and diffusion coefficient of the solute from experimental data.
