Abstract

The Generalized Corresponding States Principle (GCSP), based on the properties of two nonspherical reference fluids, offers flexibility and ease of computation for the prediction of thermodynamic and transport properties of pure fluids and fluid mixtures. In this work, the multi-fluid GCSP is used for the calculation of the critical properties of mixtures. Classes of mixtures studied include those containing: (1) simple spherical molecules; (2) large quasi-spherical molecules such as the cyclosiloxanes; (3) both spherical and large nonspherical molecules such as those important in supercritical extraction and hydrocarbon processing; and (4) molecules exhibiting strong dipole moments. The advantages of the GCSP method are outlined, particularly for fluids not usually amenable to conventional corresponding states treatments.
