What is An Improved Group Method for Hydrocarbon-hydrocarbon Systems Arising from a Comparative Study of Asog and Unifac about?
A comparison of the formalism of ASOG, in the version of Kojima and Tochigi, and of UNIFAC shows the total formal equivalence of both empirical group methods for calculating activity coefficients in mixtures. The most advantageous features of each method are taken into account in the formulation of an improved method for hydrocarbon-hydrocarbon systems. Parameters for CHJArCH, CH,/CyCH, CH&H=, ArCH/CyCH, ArCH/-CH= and CyCH/-CH-arc evaluated from total pressureliquid composition and heats of mixing data using the SIGMA procedure. The results obtained with the three empirical group methods are compared with experimental data. The ability to predict activity coefficients at infinite dilution is discussed.
