![]() ![]() The comparisons between the experimental data and the results of the new equation of state show the accuracy of the proposed equation with respect to commonly used equations of state, i.e. The capability of the proposed equation of state for predicting some other thermodynamic properties such as compressibility, second virial coefficient, sound velocity in gases and heat capacity of gases are given, too. The average deviations of the predicted enthalpy and entropy of vaporization are 2.393 and 2.358%, respectively. Also the enthalpy and entropy of vaporization are calculated by using the new equation of state. ![]() The average deviations of the predicted vapor pressure, liquid density and vapor volume for 40 pure compounds are 1.116, 5.696 and 3.083%, respectively. The parameters of the new cubic equation of state are obtained as functions of reduced temperature and acentric factor. In this work, a new two-parameter cubic equation of state is presented based on perturbation theory for predicting phase behavior of pure compounds and of hydrocarbons and non-hydrocarbons.
