A mixture (total flow rate = 100 kmol/hr) with 28 mol% n-hexane, 42 mol% n-heptane, and 30 mol% of n-octane is to be distillated to produce a distillate product with 1 mol% of n-heptane and a bottoms product with 0.5 mol% n-hexane. The column operates at 1.2 atm with 60% of feedbeing in vapor state. At 1.2 atm, the relative volatilities of hexane and heptane with respect to octane areapproximated to be 4.836 and 2.188, respectively. Calculate the number of equilibrium stages required toachieve this product specification at total reflux.2. Continue from Problem 1 and assume that the reflux ratio is 30% higher than theminimum reflux ratio.(a) Calculate the number of equilibrium stages required to achieve this product specification.
