Calculations of phase-equilibria ON-LINE   --   free


What can VLE-Calc do:

  • fast searches from a database of physico-chemical and phase-transition properties of the following materials: acetone, methanol, dichloromethane, tetrahydrofuran, water, ethanol, ethylacetate, toluene, acetic acid, isopropanol, chloroform, acetonitrile
  • draw p-T tensiondiagram for a single component
  • calculate the vapor-liquid equilibrium data of binary and ternary mixtures (ANY combination of compounds mentioned above) at ANY pressure and temperature
  • draw x-y or x,y-T and triangular equlibrium diagrams
  • predict the results of simple batch distillations of ANY binary and ternary mixtures at ANY pressure

This page is under continuous development.

Lots of great upgrades are planned in the near future, which were useful for problem solving in the chemistry and chemical engineering. So it is worth to return here and take a look what's new on VLE-Calc.com. Some of the expected updates:
  • dynamic measure unit conversion at result tables and diagrams
  • more types of triangle diagrams (e.g. residue curve map)
  • correct consideration of limited miscibility
  • drawing of x,y-p equilibrium diagram
  • calculations of liquid-liquid equilibria
  • calculations of extractions
  • calculations of continuous distillation
  • calculations of fractional distillation (rectification)
  • more and more components in the database
