MANAGEMENT AND MODELLING OF TECHNOLOGICAL PROCESSES AND TECHNICAL SYSTEMS
Mathematical modeling at the calculation of the vapor-liquid equilibrium of multicomponent systems
Yu. A. Komissarov, Dam Quang Sang Mendeleev Russian Chemically-Technological University
Abstract:
A mathematical description of equilibrium conditions in vapor-liquid mixtures with the use of the equations of Wilson, NRTL, Soave–Redlich–Kwong, Peng–Robinson and others is given in the paper. Software is developed in order to calculate and analyze the vapor-liquid equilibrium of multicomponent systems when input parameters (temperature, pressure, composition of the liquid and vapor phases) are changed. A database is created that contains important thermodynamic properties of more than 600 components for gas and liquid, parameters of the binary interaction (more than 300 pairs) in the above mentioned equations. This database was used in calculating the vapor-liquid equilibrium of multicomponent systems.
Keywords:
mathematical modeling, vapor-liquid equilibrium, multicomponent mixture, Newton–Raphson method, software, thermodynamic properties, database.
