4. A distillation column is to be designed that will separate ethanol and water at 1 atm. Use the provided xy diagrams to design a column. One feed is a saturated liquid and is 42 mol% ethanol. The second feed has a flowrate of 100 kmol/h, is 18 mol% ethanol, and 30% vapor. The distillate should be 66 mol% ethanol with a flowrate of 80 kmol/h. The bottoms should contain 4 mol% ethanol. The reflux ratio is 0.5. 1. What feed flowrate is required for the saturated liquid feed? What is the bottoms flowrate? 2. What are the internal flowrates (V, L, V', L',V, and L)? 3. Determine N, Nf1, and NF2. Points-30 0.9 08 0.7 0.6 MENCODING SO TUISBL Sort 0.5 Geno 04 DE MUSO 0.3 CCB OLGA 02 100 ESTE OL POMOGO be 0.1 APSU BLOG Dobago hour 0.1 02 03 04 0.5 0.6 0.7 0.8 0.9
