A distillation column with 100 kmol/h feed of 60% A
and 40% B produces a distillate product with xD = 0.95 and a bottom
stream with xbot = 0.04 of the more volatile species A. CMO is
valid and the equilibrium data is given by y = 2x/(1+x)
If R = 2 and q = 0.8, determine (numerically) the
composition (x) of the liquid stream entering the
reboiler).

We are separating acetone and ethanol in a distillation column with a total condenser and a partial reboiler. The column has two feeds and operates at a pressure of 1.0 atm. Feed 1 is a saturated liquid that is 60.0 mol% acetone and has a feed rate of F1 = 200.0 kmol/h. The second feed is 40.0 mol% acetone, has a feed rate of F2 = 300.0 kmol/h, and is a two-phase mixture that is 20% vapor. Assume CMO is...

The distillation column shown at the right is used to separate compound A from compound B in an adiabatic fashion. A liquid mixture of A and B is fed at a specified temperature into a distillation column (stream 1). At the top of the column, a vapor stream that is A-rich (stream 2) passes through a condenser that completely condenses the mixture. Half of this liquid leaves the condenser as the overhead product (stream 4), and half of the liquid...

QUESTION 5 A distillation column has one inlet feed (F), and two outlets, a distillate (D) and a bottom (B) stream. The inlet feed, F = 100 kg/h, of ethanol and water, has an ethanol mass fraction of xF = 0.5. The distillate flow rate is 85 kg/h, and the bottom ethanol mass fraction is xB = 0.38. What is the total bottom flow rate, B, in kg/h?

The vapor-liquid equilibrium for n-pentane and n-hexane at 1 ATM is well approximated using a constant relative volatility of 2.95. CMO is valid. For all the problems, the feed stream is flowing at 80 mol/s and contains 45 mol% n-pentane, the feed is a saturated liquid (q = 1) at the column pressure, the distillate is 95 mol% n-pentane, and the bottoms is 10 mol% n-pentane. In this problem, you should analyze the column graphically using the McCabe-Thiele Method a....
