Questions: The distillation column has two feeds at their ideal feed stages. One feed is 100kmol/h at 42 mole \% n-hexane at 30% fraction vaporized, and the other feed is 200kmol/h at 62mole%n hexane with 125% liquid. The column has a partial condenser with a vapor distillate at 96 mole \% n-hexane and a saturated liquid reflux. The column has a partial reboiler and a bottoms product of 4.0 mole % n-hexane. 1. Find the minimum number of stages for this separation. 2. Find the minimum reflux ratio based on the 62 mole %n-hexane feed. 3. The column operates at three times the minimum reflux ratio. Find the liquid and vapor molar flowrates in each section of the column. 4. Find the number of equilibrium stages and trays needed in the column. 5. Plot the liquid and vapor molar flowrates leaving each stage, the liquid and vapor mole fractions n-hexane leaving each stage (two decimal places), and the temperature for each equilibrium stage (no decimals)
