摘要：

A method is proposed for calculating the axial impurity profile in a crystallization column and assessing the effectiveness of the purification of a substance via counterflow melt crystallization. The method takes into account the combined effect of diffusion and crystallization processes. An approximate equation for the separation factor is derived. The results obtained for a few systems agree well with experiment.
