Themodynamic consistency for the experimental data was examined by using point by point test, and the fugacity coefficients of components in the vapor phase were calculated by Hayden-O’connell method. Finally, use MATLAB toolbox function back to return the Van Laar, Wilson and NRTL model parameters and correlation deviation. For NRTL model, the average absolute deviation in vapor-phase is 0.0027, and the average absolute deviation of the equilibrium temperature is 0.2583℃. 目 录 目 录
