A Promising Method for Separating Binary Methanol–Water Solutions

Abstract

A technological scheme for drying binary solutions, which allows separating two-component solutions and complex systems using molecular size difference (molecular sieves), has been designed. Analysis of modern adsorbents produced by the domestic chemical industry was carried out, and the optimal parameters of the investigated zeolite adsorbents were determined for the regeneration and cooling processes that accompany the restoration of the adsorption properties of the adsorbents used. A mathematical model for calculating the adsorption of a water-methanol mixture on solid adsorbents has been developed and can be used for other processes, for example, for the drying of alcoholic solutions with components of polyhydric alcohols and water. A technique for calculating the separation units for binary systems is proposed.
