Q2:
The feed to a distillation column is separated into net overhead product containing
nothing with a boiling point higher than isobutane and bottoms containing nothing
with a boiling point below that of propane.
Hint: In the overhead there is no n-C5H12 or n-C4H10, and in the bottoms there in no
C2H4, C2H6, or C3H6.
The composition of the feed is

The concentration of isobutane in the overhead is 5.0 mole percent, and the
concentration of propane in the bottoms is 0.8 mole percent.
1. Draw a completely labeled flowchart for the above process
2. Do the degree of freedom analysis for the overall process
