Properties of Binary Mixtures: The Evaluation Sequence
Phase-Equilibrium Properties:
Characteristics of phase-equilibrium data evaluated in TDE:
- VLE, LLE, and SLE involving 2 phases only
- Activity coefficient models are applicable
- Properties/Variables are temperature, pressure, composition & activity coefficient
- Properties for supercritical ("fluid") phases are not considered
Derived Phase-Equilibrium Properties:
Azeotropic temperature, K
Azeotropic pressure, kPa
Azeotropic composition, mole fraction
Eutectic temperature, K
Eutectic composition, mole fraction
Lower consolute temperature, K
Lower consolute composition, mole fraction
Upper consolute temperature, K
Upper consolute composition, mole fraction
- Properties evaluated by TDE are accessed through the Multi-Property Equations and Calculated with multi-property equations nodes of the Navigation Tree.
- Properties gleaned from the literature are accessed through the Experimental Data (Display Only) node of the Navigation Tree
Single Properties (p near saturation or 101.3 kPa):
Excess Volume, m3/mol (Densities for mixtures are converted to excess volumes by TDE)
Excess Enthalpy (i.e., the Enthalpy of Mixing), kJ/mol
Viscosity, Pa×s
Thermal Conductivity, W/m/K
Surface Tension, N/m
Critical Temperature, K
Critical Pressure, kPa
