The mixture of A (LK equivalent) and B is to be separated through the distillation column connected with the total condenser and the partial reboiler. When the specified-liquid feed (F; 100 mol/h) containing 50 mol% of A is supplied and is operated through the design conditions below. The composition of A in distillate(D) was 0.96 and the composition of A in bottom(B) was 0.18

(a) Calculate Total equilibrium units (including partial reboiler)
(b) Calculate the location of the raw material supply (a number of positions down from the top plate);
(c) calculate the slope for each control line.

However, the relative velocity (αA-B) of A and B is 2.57, and the answer (a) and (b) is an integer.
Design conditions: The operating reflux ratio is set at 1.83 times the minimum reflux ratio (Rmin).

A binary mixture of benzene and toluene will be separated by continuous distillation. The mixture consists of 20% mol of benzene and 80% mol of toluene at the bubble point of 91ºC. The binary mixture is available at 100 mol h-1 and the separation should deliver a distillate product that has a concentration of 90% mol of benzene and that contains half of the benzene in the feed stream. a) Plot the equilibrium line for benzene. b) Determine the minimum...

A mixture of hydrocarbons is separated with two distillation columns in series. This mixture, containing 20 mass% ethane, 40 mass% propane and 40 mass% butane, is fed to the first column a rate of 100 moles per hour. The overhead product from the first column contains 95 mole% ethane, 4 mole% propane and 1 mole% butane. The bottoms product from the first column is sent to the second column for further separation. The composition of the overhead product from the...

A 60% mole Benzene and 40% mole Toluene mixture is sent to a distillation column, where it is separated into two equal streams.

A 60% mole Benzene and 40% mole Toluene mixture is sent to a distillation column, where it is separated into two equal streams. Calculate the composition of each stream, if the amount of benzene out of the top is 3 times greater than out the bottom.

After fermentation, a mixture of ethanol and water is sent to a small distillation column. At the top of the distillation column, a 95% ethanol solution at 65°C is produced at a flow rate of 3.5 kg/s. Your job is to design a double-pipe heat exchanger that will cool the 95% ethanol mixture to 40°C by using cooling water that is available at 10°C. Assume an outlet temperature of the cooling water of 55°C, and only use Schedule 40 pipe...
