The binary parameters of the seven natural-gas related mixtures, i. e. , CH_4 + C_2H_6 system, CH_4 +C_3H_8 system, CH_4+n-C_4H_10 system, CH_4+i-C_4H_10 system, CH_4+N_2 system, CH_4+CO_2 system and CH_4 + H_2S system, have been correlated as a function of temperature based on the experimental data of the vapor-liquid equilibrium. The critical curves and the dew-and bubble-point curves for these seven binary mixtures have been calculated by the Peng-Robinson equation of state and compared with the experimental data, which show good predictability of the equation of state. The critical points and the dew- and bubble-point curves for natural gases from six different districts have been predicted as methane-base multicomponent mixtures by the Peng-Robinson equation of state.
