VLE-Calc.com − still going − phase diagrams and distillation calculation
The program, rewritten in 2019, still welcomes new and old dear users. There are plenty of charts and materials, and hopefully the planned updates can be realized in 2025 finally. I planned for example Antoine constant calculator, liquid density temperature-functions, as well as custom molecule entry, and something like these. We will see soon. :) Changes so far 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.
VLE-diagram
Vapor pressure or boiling temperature in function of mixture composition. Binary or ternary mixtures.
Azeotrope.info
Azeotrope data of binary/ternary mixtures (azeotropic boiling point or vapor pressure, and the azeotropic composition).
Distillation calculation
Model calculations on batch distillation or continuous distillation process (flash).
