Abstract

Data quality assessment procedures for various types of phase equilibrium data are reviewed and analyzed. Experimental data for vapor-liquid equilibrium (VLE), liquid-liquid equilibrium (LLE), solid-liquid equilibrium (SLE), infinite dilution activity coefficients (ACT), and excess enthalpy (HE) are used for inter-property consistency checks, together with relevant properties of pure compounds. These procedures are essential for validation of experimental data and development of high-fidelity prediction and correlation models. A single framework involving consistency tests for all types of phase equilibria data is proposed, together with an algorithm implementation.
