Application of the Riccati Equation to Solve Binary Distillation Problems

Computes number of stages of a column

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages using the equilibrium curve and the operating line. With this second approach, we find four plates too I agreement with the Riccati equation method.
