Thermophysical properties correlations and pseudocomponent characterization parameter estimation for fossil fluids. Second annual report, September 1, 1984-August 31, 1985. [Nonpolar, polar and associating fluids; gases and vapors at low pressure]
This report summarizes work performed during the period September 1, 1984 through August 31, 1985. During this period, the companion correlations for dilute-gas viscosity and thermal conductivity have been developed. Both correlations are applicable to nonpolar, polar and associating fluids. The correlations require four characterization parameters as input, namely, critical temperature, critical volume, acentric factor, and dipole moment. One important feature of these correlations is that none of the characterization parameters has to be regressed from experimental viscosity or thermal conductivity data. This feature allows for apriori prediction of dilute gas viscosity and thermal conductivity. The correlation for dilute gas viscosity eta/sub 0/ uses the Chapman-Enskog expression. The main departure from other earlier work on eta/sub 0/ includes the use of the Stockmayer potential for polar and associating compounds. The dipole moment, along with molecular weight, critical temperature, critical volume and accentric factor, was found to be adequate in characterizing both polar and associating fluids studied in this work. A total of 757 data points were used covering 14 nonpolar, 11 polar, and 7 associative fluids. The overall deviation is 1.37%. A detailed description of the correlation is given in Appendix A. The correlation for dilute gas thermal conductivity presented uses a modified Mason-Monchick expression. It uses the same characterization parameters as those for the viscosity correlation. A total of 1136 data points were used in testing the correlation. The overall deviation is 5.44%. A detailed description of the correlation is given in Appendix B.
