D13.* We have a column separating benzene, toluene, and cumene. The column has a total condenser, a total reboiler, and nine equilibrium stages. The feed is 25.0 mol% benzene, 30.0 mol % toluene, and 45.0 mol% cumene. Feed rate is 100 mol/h, and the feed is a saturated liquid at 1.0 atm. The column pressure is 1.0 atm. The equilibrium data can be represented as constant relative volatilities: авт 2.5, ATT = 1.0, and act 0.21. We desire 99.0% recovery of toluene in the distillate and 98.0% recovery of cumene in the bottoms. = = a. Determine the required external reflux ratio. b. If aBT = 2.25 instead of 2.5, what is the value of L/D?

Question
Transcribed Image Text:D13.* We have a column separating benzene, toluene, and cumene. The
column has a total condenser, a total reboiler, and nine equilibrium
stages. The feed is 25.0 mol % benzene, 30.0 mol% toluene, and
45.0 mol% cumene. Feed rate is 100 mol/h, and the feed is a
saturated liquid at 1.0 atm. The column pressure is 1.0 atm. The
equilibrium data can be represented as constant relative volatilities:
ABT = 2.5, ATT = 1.0, and act 0.21. We desire 99.0% recovery of
toluene in the distillate and 98.0% recovery of cumene in the
bottoms.
a.
Determine the required external reflux ratio.
b. If aBT = 2.25 instead of 2.5, what is the value of L/D?
