4.0 kmoles of a feed that is 0.60 mole fraction acetone and 0.40 mole fraction ethanol is batch distilled in a system with a still pot (an equilibrium contact), a column that acts as one equilibrium stage (total two equilibrium contacts), a total condenser, and reflux to the column. \(\mathrm{p}\) \(=1.0 \mathrm{~atm}\), the reflux ratio is \(\mathrm{L} / \mathrm{D}=1.0, \mathrm{CMO}\) is valid, and \(\mathrm{x}_{\mathrm{W}, \text { fin }}=0.20\). VLE data are in Problem 4.D7. Find \(\mathrm{W}_{\text {fin }}, \mathrm{x}_{\mathrm{D}, \text { avg }}\), and \(\mathrm{D}_{\text {total }}\).

Problem 4.D7.

Transcribed Image Text:

D7.* A distillation column with a total condenser is separating a feed that is 30 mol% acetone from ethanol. Distillate xD = 0.90, and bottoms XB = 0.13, both mole fractions acetone. Assume CMO is valid. L/V = 0.8. Boilup ratio is
