| Abstract: | Substituting the average value of correlations for predicting Tc of non-hydrocarbons and the correlations for predicting Pc and Vc into the critical compressibility factor definition equation, Zc=(PcVc)/(RTc) leads to the following correlation for estimating Zc asZc=0.259+40/(R(MN)0.5(1.27660+92.76/(Tb)))By combining the experimental values of 133 non-hydrocarbons' critical compressibility factors and the method of least square regression, we obtain the correlation for predicting Zc as follows:Zc=0.2772-0.533/((MN)0.5(1.27660+92.76/(Tb))) |
