4. Azeotropic distillation

4.1 Using residue curves to design distillation units

Established at full reflux, the equation of a residue curve is determined from a global and partial material balance on the boiler of a simple evaporator:

\frac{d x_{i}}{d τ} = (x_{i} - y_{i}) i = 1 \dots n Courbes de résidu
