Современные возможности определения равновесного состава многокомпонентных химических систем

Современные возможности определения равновесного состава многокомпонентных химических систем

Abstract

В работе раскрыты современные возможности определения равновесного состава многокомпонентных химических систем на базе метода термодинамического моделирования. В основе термодинамического моделирования лежит предположение о достижении полного равновесия во всей системе в целом либо локального равновесия в отдельных ее частях. Поиск экстремумов различных функций как метод оптимизации технологических процессов находит широкое применение в различных отраслях науки и техники, в том числе и в процессах, связанных с химией, металлургией, экологией и др. Метод максимизации энтропии, рассматриваемый в данной работе, позволяет проводить термодинамическое моделирование реальных систем при любых параметрах состояния. Результатом термодинамического моделирования может являться определение равновесного состава, расчет выхода целевого продукта, определение неизвестных термодинамических параметров процессов, вычисление свойств различных сред и многое другое.

Modern capabilities of determining equilibrium composition of multicomponent chemical systems on the basis of the thermodynamic modeling method have been considered. The supposition about full equilibrium in the system as a whole or local equilibrium in its separate parts is the basis of thermodynamic simulation. Extremum seeking of different functions as a method of processing optimization finds application in different branches of science and engineering, including chemistry, metallurgy, ecology etc. The method of entropy maximization considered in the paper allows to conduct thermodynamic simulation of systems with any parameters of their state. The result of thermodynamic simulation can be determination of equilibrium composition, calculation of main product output, definition of unknown thermodynamic parameters of processes, calculation of properties of different media and many other things.
