Approximate LLE calculations
This page will generate approximate ternary LLE diagrams
starting from the mutual solubility of a pair of partially miscible
species.
Users should be aware of the basic assumptions:
- One substance (component 3) is pefectly miscible with both other
species and forms ideal mixtures with them. Conseqeunce:
The concentrations of this component in both species in both
phases are assumed equal (and so the tie lines
are horizontal).
- The partially miscible pair (components 1 and 2) are modelled
by the 1-parameter Margules equation. Consequence:
The solubilities of 1 in 2 and of 2 in 1 are
assumed equal.
