VLE-Calc.com has been renewed − phase diagrams and distillation calculation

After 5 years of development a completely rewritten and redesigned program is released. More materials and more types of charts are built-in, and an easier-to-use interface (which is more mobile-friendly) has been formed. All the details of changes can be found in the version history section.

Main applications of vapor-liquid equilibrium calculations

Pure compound properties

Boiling point, heat of vaporization, heat capacity, vapor pressure, critical data, e.t.c.
* NEW SUBSTANCES *  amines, heterocycles, gases (supercritical components!)

VLE-diagram

Vapor pressure or boiling temperature in function of mixture composition. Binary or ternary mixtures.

* Supercritical components are handled from now! (with PSRK- EOS)
* Residue curve map

Azeotropic data

Search for azeotrope data of any binary or ternary mixture (azeotropic boiling point or vapor pressure, and the azeotropic composition).

Distillation calculation

Model calculations on batch distillation or continuous distillation process (flash).

Other phase equilibria and process modeling

Solubility of solids

Calculation of solubility of organic solids in pure or mixed solvents. Generation of solubility tables and charts, diagrams.

Liquid miscibility

LLE model calculations, phase diagrams of immiscible or partially miscible organic solvents.

* More advanced LLE-algorithm: detects metastable zones, avoids false tie lines, and detects three-phase regions!

Process flow diagram

Calculates material flow and draws flowsheet of chemical batch processes using process simulation.
