THE DETERMINATION OF KIHARA POTENTIAL PARAMETERS FROM GAS HYDRATE DATA

A consistent methodology is presented for obtaining unique values for the Kihara potential parameters from gas hydrate data. For nearly perfect gases, the values of these parameters are justified by favourable comparisons of predicted second viral coefficients with experimental data. It is demonstrated that the parameters determined may be used with the ideal solid solution model of van der Waals and Platteeuw to predict reliably hydrate dissociation pressures as well as hydrate compositions.
