Generating LLE graphs

This page will generate approximate ternary Liquid Liquid Equilibria diagrams starting from the solubilities of a pair of partially miscible species.

Users should be aware of the following basic assumptions:

  • The partially miscible pairs are modelled by the 2-parameter Margules equation.
  • The Margules constants A' and B' actually refer to A/RT and B/RT.

Here is a basic version
