4. Ternary diagrams of residual curve networks

The analysis of ternary residue curve diagrams is at the heart of design tools for azeotropic or extractive distillation units for non-ideal mixtures. The addition of one-third body E to the A-B mixture enables ternary A-B-E diagrams to be plotted and analyzed graphically.

4.1 Representation of ternary liquid-vapor equilibria

The three-dimensional representation of the bubble [T b,p (x )] and dew [T d,p (y )] surfaces as shown in figure 10 a is the most complete but is difficult to exploit. For its part, the projected equilibrium vectors...
