McCabe-Thiele Method for an Ideal Binary Mixture

The program computes the number of equilibrium stages for a binary ideal mixture with relative volatility equal to 2.45. The feed is a two phase mixture with a feed quality is equal to 0.85. The distillate, feed and bottom mole fractions are 0.9, 0.5 and 0.1, respectively. The reflux ratio is taken to be 1.51435 . We draw the McCabe and Thiele Diagram and get the number of theoretical plates equal to 9. A similar code using Mathematica 6.0 is available at the following link:
