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!)
![substances](erlyflask.jpg)
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.
![solid solubility](SLE-diagram.png)
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.
