1. A distillation column with two feeds is separating ethanol from water. Ihe frst feed is 60.0wt% ethanol, has a total flow rate of 1000.0kg/h, and is a mix of liquid and vapor at 81C. The second feed is 10.0wt% ethanol, has a total flow rate of 500.0kg/h, and is liquid at 20C. Bottoms product is 0.01wt% ethanol, and distillate product is 85.0 wt% ethanol. The column operates at 1.0kg/cm2 and is adiabatic. The column has a partial reboiler, which acts as an equilibrium contact, and a total condenser. The distillate and reflux are saturated liquids. Find B and D in kg/h, and find Qc and QR in kcal/h. Use data in Figure 2-4. a. External reflux ratio, Lo/D=3.0 (mass units). b. Boilup ratio, V/B=2.5 (mass units)
