In addition, Aspen Plus stores a large database of interaction parameters that are used with mixing rules to estimate mixtures properties.

Thus, the surface tension of the mixture . It also provides an assessment of surface tension models. It then looks at adsorption of solutes on liquid metallic surfaces; equations for the surface tension of binary liquid mixtures; methods of surface tension measurement; and experimental data for the surface tension of liquid . The liquid interfacial tension was measured in the liquid–liquid equilibrium range at the same conditions of temperature and pressure. A new equation is proposed to correlate the excess surface tension of binary mixtures. This equation can be obtained from the Butler equation and correlates well the excess surface tension by:

The surface tension of a liquid mixture is an important property in process design, because it plays an important role in affecting the mass and heat transfer at the interface. Critically reviewed surface tensions of pure liquids, ranging from the melting to critical temperature, are available for a great number of substances.

In contrast, experimental data for liquid mixtures are extremely scarce, even though the liquid materials Cited by: Surface Tension of Pure Liquids and Binary Liquid Mixtures: Supplement to IV/ : Wohlfarth, Christian, Lechner, Manfred Dieter: Libri in altre lingueFormat: Copertina rigida.
