✦ Synopsis

Ah&act-A generalised multtiuid corresponding slates principle is presented for the correlation and prediction of the thermodynamic properties of fluid mixtures. The multifluid model is an extension of earlier work which was based on the known properties of two (nonspherical) reference fluids. The new model is tested for the prediction of the orthobaric densities of LNG mixtures using all the pure components as the reference fluids. Comparisons with the two-fluid corresponding states method are shown and the advantages and disadvantages of the two methods are outlined. For simple nonpolar mixtures, such as LNG. both methods can give predictions which are well within the accuracy of the experimental data using, at most, only one adjustable coefficient to characterize each binary system.

The principle of corresponding states is a sound but limited principle from which to predict the thermodynamic properties of pure fluids. We describe formal extensions of the principle to cover wide classes of fluids and their mixtures. These extensions are made in a general form, from which most pr
