Thermodynamic and transport properties for polar coal mixtures. Technical progress report, July 15-December 31, 1984
Progress has been made towards the goal of developing relationships for the calculation of the thermodynamic and transport properties of polar coal mixtures. The initial phase of this work has involved the extension to polar systems of procedures for the calculation of thermodynamic properties of nonpolar mixtures from parameters of the components. The mixture constants and their composition derivatives are calculated from the relationships outlined. In Table I, values of ..gamma../sub i/ /sup infinity/, calculated by these procedures for acetone-hydrocarbon mixtures are compared with experimental values resulting from extrapolated vapor-liquid equilibrium data or gas chromatographic experiments. It can be seen that generally good agreement is obtained. In Figure 1, values of the heat of mixing, ..delta..H/sub Mix/, calculated with the equation of state of Wu and Stiel and the constants T/sub CM/, ..omega../sub M/, and Y/sub M/ for liquid mixtures of 2-butanone and n-hexane at 298.15/sup 0/K are shown to be in good agreement with the experimental values. Similar comparisons are shown in Figure 2 for the heat of mixing of acetone-n-hexane mixtures at 243.15/sup 0/K. In Figure 3, calculated bubble point and dew point pressures for acetone-n-hexane mixtures at 318.15/sup 0/K are shown to agree closely with the experimental values. 7 references, 1 table and 3 figures.
