For the column shown in Problem 3.D2, derive equations for $D, B, Q_{c}$, and L/D.

D2.* A distillation column separating ethanol from water is shown in the

D2.* A distillation column separating ethanol from water is shown in the following figure. Pressure is 1 kg/cm2. Instead of having a reboiler, 100 kg/min of saturated steam (pure water vapor) is injected directly into the bottom of the column to provide heat. Feed rate is 100 kg/min of 30 wt % ethanol at 20C. Reflux is a saturated liquid. Distillate concentration is 60 wt % ethanol, and bottoms product is 5 wt % ethanol. What is the external reflux ratio, L/D? Qc V Qcol = 0 L D,XD F,z Ys,S B,XB
