Objects of research: technological processes in the rectification unit. Purpose of work: To develop mathematical methods of to calculating the experimental and statistical models in describing vapor-liquid equilibrium of multicomponent mixtures, the development of mathematical models of distillation alcohol mixtures, providing a reliable convergence of algorithms, determination of optimal design and technological parameters of distillation columns, rectification installation modernization and automatization of production. Methods of research: In this thesis there are used the methods of mathematical modeling of phase equilibrium of binary and multicomponent mixtures, as well as the processes of separation of multicomponent mixtures, and methods to ensure the convergence of iterative schemes for equations of mathematical description of the process of rectification of multicomponent mixtures. The findings and their novelty: It is solved the problem of approximation of physical and chemical properties of functional dependencies; the software implemented version of the algorithm for calculating conditions of phase equilibrium are developed; a mathematical model of rectification, taking into account the interaction of all components of the alcohol mixture with variable flows of vapor and liquid height of the column is developed; a method for calculating process of rectification of multicomponent mixtures, proposed modernized scheme BRU is developed. Practical value: is to develop a mathematical model of multicomponent distillation. The developed algorithms and software can be used to calculate the vapor-liquid equilibrium and calculation columns of rectification of any multicomponent mixture. Field of application: the results of research work and developments can be used at the alcohol industry companies with the continuous nature of production.
