b. Boilup ratio, V/B=2.5. A distillation column is separating ethanol from water at a pressure of 1kg/cm2A two-phase feed of 20wt% ethanol at 93C is input at 100kg/min. The column has a total condenser and a partial reboiler. The distillate composition is 90wt% ethanol. Distillate and reflux are at 20C. Bottoms composition is 1wt% ethanol. Reflux ratio is L0/D=3. A liquid side stream is withdrawn above the feed stage. Side stream is 70 wt % ethanol, and side stream flow rate is 10kg/min. Find D,B,Qc, and QR. Data are in Figure 2-4
