2) (40 total points) We are separating n-butanol and water in a single distillation column with two feeds and a liquid-liquid separator. Feed 1 is 37.0 mol% water, the flow rate is F1 = 50.0 kmol/h, and it is a two-phase feed that is 45.0% vapor. Feed 2 flow rate F2 = 75 kmol/h and it is a saturated liquid that is 20.0 mol% water. The column has a partial reboiler and total condenser. The water product (flow rate = Dw kmol/h) is from the aqueous layer from the liquid-liquid separator at Xa. The butanol product (flow rate = BB kmol/h) is bottoms from the distillation column, and the water mole fraction is 0.04. The boilup ratio is 2/3 (Vbar/B). Find the flow rates of the products, Dw and Bg. Find the optimum feed stage locations and the total number of stages. Step off stages from the top down. The reflux is the organic phase from the liquid-liquid settler at XB. a) Draw the process flow sheet (10 pts) b) Find the flow rates of the products, Dw and BB (15 pts) c) Find the optimum feed stage locations and the total number of stages. Step off stages from the top down. (15 pts)
