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).

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.

Process flow diagram

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