This provides extensive computer programs, which are also available from Professor Prausnitz (U. of California, Berkeley) for a nominal fee, I believe.

    Vapor-liquid equilibria data for binary mixtures were isobarically obtained with a modified Fischer cell at kPa. The vapor and liquid phase compositions were analyzed with a gas chromatograph. The methodology was initially tested for cyclo-hexane+n-heptane data; results obtained are similar to other data in the literature. Vapor-liquid equilibria form the basis of various kinds of chemical engineer­ ing calculations. In particular this is true for the design of certain separation processes, such as distillation and condensation. For the large number of computations of this kind vapor-liquid equilibrium data for the systems to be handled are Size: 3MB.

VLE - Vapor-liquid equilibria (normal boiling points of all components above 0 °C); HPV - Vapor-liquid equilibria (normal boiling point of at least one component below 0 °C); ELE - Vapor-liquid equilibria (systems containing solved electrolytes).

UNIFAC uses the functional groups present on the molecules that make up the liquid mixture to calculate activity coefficients. By using interactions for each of the functional groups present on the molecules.

Solid-Liquid Equilibria Using UNIFACCited by: The group contribution method UNIFAC has become very popular because of its large range of applicability and its reliable predictions of vapor−liquid equilibria.

With the help of new data stored in the Dortmund Data Bank (DDB), many gaps in the existing UNIFAC parameter matrix have been filled, and many new main groups have been added to the parameter by:.

7 Vapor-Liquid Equilibria and Saturation Prof. Manolito E Bambase Jr. Department of Chemical Engineering. University of the Philippines Los Baños SLIDE 5 Definition of Terms Saturated Vapor and Saturated Liquid Vapor and liquid at the saturated P and saturated T.

Subcooled Liquid A liquid that is below its saturated T at a given pressure.In thermodynamics and chemical engineering, the vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase.

The concentration of a vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be a partial pressure (a part of the total gas pressure) if any other gas(es.Summary: A liquid containing 12 mol% pentane (x = ) could be heated to K at which point it would start to boil (blue line).The saturated vapor (red line) in equilibrium with the boiling liquid is at the same temperature, but is richer in the more volatile component, composition of this saturated vapor is 40 mol% n-pentane (y = ).
