McCabe-Thiele diagrams fractional extraction

This result is very close to that obtained by using a McCabe-Thiele diagram (Fig. 15-23). From solubility data at Y = 0.1039 kg acetic acid/kg MIBK (given in Table 15-8), the extract layer contains 5.4/85.7 = 0.0630 kg water/kg MIBK, and Ye = (0.097)/( 1 -t- 0.097 -t- 0.063) = 0.084 mass fraction acetic acid in the extract.

Since liquid-liquid equilibrium is seldom available in algebraic form, the calculations tend to be iterative or graphical. A modified McCabe-Thiele approach can be used if y data versus x data are available. The coordinates for the diagram are the mass fraction of solute in the extract phase and the...
