First, the pure component influence parameters of CH4, N2, CO2 and H2O are obtained. Then, temperature-dependent expressions of binary interaction coefficient for (CH4+H2O), (N2+H2O) and (CO2+H2O) are correlated. These empirical correlations of pure component influence parameters and binary interaction coefficients are applied for ternary mixtures. For (CH4+N2)+H2O and (N2+CO2)+H2O mixtures, the predictions show good agreement with experimental data (overall AAD∼1.31%).
