a) A distillation column operating at 14 bar with a saturated liquid feed of 1000kmol/h with composition given in Table 1 is to be separated into an overhead product that recovers 98% of the n-butane overhead and 95% of the i-pentane in the bottoms. Relative volatilities are also given in Table T1. i. Calculate the minimum number of stages using the Fenske Equation. ii. Estimate the compositions of the overhead and bottoms products using the Fenske Bquation. iii. Calculate the minimum reflux ratio using the Underwood Equations
