Non-Ideal x-y Diagrams

This page enables x-y diagrams to be plotted for binary systems. It is primarily intended to calculate and display vapour liquid equilibrium for azeotropic pairs of components. To this end, it is possible to display a window from which azeotropic data may be exported to this window.

There are several approaches for calculating Vapour - Liquid equilibrium available:


All calculations are carried out at 1 atmosphere.
NB: There are approximations ...
