Continuous Multistage Binary Distillation

● TECHNICAL DESCRIPTION

propane n-butane
Feed composition : 0.5 0.5
Distillate composition : 0.9 0.1
Bottoms composition : 0.1 0.9

Feed rate : 100moles/h
Thermal condition of feed : q = 0.2
Murphree vapor efficiency : EMV = 0.70
Entrainment : ε = 0.10
External reflux ratio : L/D = 2.0
Operating pressure : 220 psia

Distribution coefficients (K = Y/X) :
ln K = A/T + B + CT , where T = [ °R ]

at 220 psia, the values of the constants :
A B C
propane -3987.933 8.63131 -0.00290
n-butane -4760.751 8.50187 -0.00206

● PROBLEM

1. Using the above information calculate
① Flow rates of all streams
② Bubble point temperature of liquids from each stage (including reboiler)
③ Composition of liquid vapor streams from each stage
④ Number of stage needed for required separation
⑤ On which stage(including from the bottom of the column) is the feed introduced
2. Repeat ①, but set the entrainment equal to 0.0 throughout the column.
What effect does this have on the number of stage required?
3. Repeat ①, but set the efficiency equal to 1.0 what is the effect of this change?
4. Repeat ①, but use L/D = 30.0. What is effect of this change?
5. Repeat ①, but use L/D = 1.5. What is effect of this change?
