It is desired to design a distillation column to separate Methanol and Ethanol. One must obtain 100 kmol / hr of distillate with a mol concentration of 0.95 from a liquid stream saturated with 35 mol% of methanol. For this purpose, there will be a Reboiler and a total capacitor that can eliminate 12000 Kcal / h (λ = 40Kcal / Kmol), and allows a return flow of saturated reflux to the tower. If the concentration of bottom product should not exceed 5 mol% of methanol.

Determine
a) The kmol / hr of food and funds.
b) The number of theoretical stages required.
c) The optimal location of the feeding plate.

The equilibrium curve for the methanol-ethanol system is given by the following equation:
y = 4x / (1 + 4x)

Q1) Methanol (50 %) and water (50 %) mixture is fed into a distillation column. The feed flowrate is 500 kmole/hr. 50 % of feed is vaporized. The column is well insulated and has a total condenser. A reflux is set to 2 and returned to column as saturated liquid. The compositions in the distillate and bottom are to be 95 % and 5 %, respectively. The column is at 1 atm. Instead of a reboiler, saturated steam is directly...

We wish to separate a mixture of 60 mol% ethanol and 40 mol% n-propanol in a distillation column with a partial reboiler and a total condenser. The feed rate is 1000 kmol/h, and feed is a saturated vapour. We desire a distillate product of 99 mol% ethanol and a bottoms product that is 0.8 mol% ethanol. Reflux is saturated liquid and CMO can be used. Equilibrium data can be approximated with an average relative volatility of 2.1 (ethanol is more...

Consider the distillation of a saturated liquid feed of 0.16 mol fraction methanol and 0.84 mol fraction water. The column has a side stream of composition 0.5 mol fraction methanol and a flow rate of 7.7% of the feed rate. The top product is to contain 0.77 mol fraction methanol and the bottom product is to contain 0.02 mol fraction methanol. The column operates at 1 atm, and the usual simplifying assumptions can be made. The external reflux ratio is...

A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of xD = 0.90 mole fraction acetone is desired. Since CMO is valid, L/V = constant. If L/V is equal to 0.8. The distillation column has a partial reboiler that acts as an equilibrium contact. If the bottoms composition is xB = 0.13 mole fraction acetone and the boilup ratio V/B= 1.0, find the vapor composition leaving the second stage above the partial reboiler. a)...

Separation of Acetone and Ethanol A distillation column with a total condenser and partial reboiler is separating acetone and ethanol (equilibrium data is provided in the table below). The feed is 70 mole% acetone, flows at 1000 mol/h, and is a superheated vapor for which one mole of liquid must be vaporized on the feed plate to cool four moles of feed. We desire a bottoms composition of 5 mole% acetone and a distillate composition of 90 mole% acetone. The...

Fifty mol% methanol in water at 101 kPa is continuously distilled in a seven-plate, perforated-tray column, with a total condenser and a partial reboiler heated by steam. Normally 100 kmol/h of feed is introduced on the third plate from the bottom. The overhead product contains 90 mol% methanol, and the bottoms 5 mol%. One mole of reflux is returned for each mole of overhead product. Recently it has been impossible to maintain the product purity in spite of an increase...

Distillation- McCabe-Thiele A saturated vapor feed (pure vapor at the dew point) containing 52 mol% toluene and 48 mol% n-octane is to be fractionated at 101.3 kPa abs. to give a distillate containing 95 mol% toluene at 10 kmol/hr and a bottoms containing 5 mol% toluene. Use McCabe-Thiele graphical method to answer the following questions: a) Draw a vapor-liquid equilibrium diagram. Do this in excel and use gridlines to produce a nice figure that you can use for the rest...
