![]() ![]() The methods used in the study: thermodynamic models in HYSYS software such as Peng-Robinson equation of state, Lee-Kesler-Ploc-ker equation of state, NRTL equation, Grayson-Streed semi-empirical model method of statistical mechanics (Chapman-Enskog method) method of corresponding state (Golubevfs method) similarity theory. #Aspen hysys free download full version software# The authors have studied the features of separation modeling in hydrocarbon media within the thermodynamic equilibrium and discussed the approaches to calculation of phase equilibrium in multicomponent systems. Regularities and peculiarities of changes in structure of gas mixture depending on temperature and pressure were studied. ![]() It was shown that for some separation modes there are conditions of non-monotonic change of structure with extremums that influence significantly the physical properties and intensity of exchange processes of heat and mass transfer in multicomponent hydrocarbon media. ![]() The authors calculated thermal and physical properties of gas mixture by different methods. #Aspen hysys free download full version plus#. ![]()
