High Pressure Vapor-Liquid Equilibria: The Interaction between Theory and Experiment
The development of accurate correlations for the calculation of high pressure vapor-liquid equilibria necessitates an investigation into the type of experimental data needed to test the correlations and the development of proper data reduction methods which the experimental data must be subjected to. First, there will be a discussion of the type of experimental data needed to develop correlations for the calculation of high pressure vapor-liquid equilibria and of how the simplest possible correlation can be developed which also gives an accurate representation of the experimental data. Second, it will be demonstrated that isothermal high pressure vapor-liquid equilibria data can be subjected to a thermodynamic consistency test in accordance with the isothermal Gibbs-Duhem equation. Third, there will be a short review of some of the most recently developed high pressure vapor-liquid equilibria correlations with engineering application.
