This simulation shows how to use the Hunter-Nash method on a right-triangle ternary phase diagram. The Hunter-Nash method uses material balances and a ternary phase diagram with phase separation to determine the number of equilibrium stages needed for liquid-liquid extraction (LLE). The solvent mass flow rate and the desired raffinate (refined product) composition R N are given. Use buttons to view the compositions of the feed F, solvent S, or raffinate RN in the solute (blue), solvent (red) and carrier (green) phases. This simulation displays a schematic of the flow system and mass balances.
