Description of multicomponent rectification based on extended principle of maximum entropy

The paper is concerned with features of the rectification process calculation for non-ideal mixtures in which non-ideal properties appear only as the difference in sizes of microparticles (athermal mixtures). The method is based on principle of maximum entropy. The information entropy of the complex experiment involving conditional probabilities and terms of entropy is used as the plausibility criterion. It is revealed connections between the activity coefficients of the athermal mixture and relative volumes of microparticles.
