: 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-CsH12 or n-C4H10, and in the bottoms there in no C2H4, C2H6, or C3H. The composition of the feed is mole % Ethylene 2.0 Ethane 3.0 Propylene 5.0 Propane 15.0 Isobutane 25.0 n-Butane 35.0 n-Pentane 15.0 Total 100.0 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 3. Assuming a basis of 100 moles of the feed, calculate the composition of the overhead and bottoms streams. 4. Scale up the process for 2255lbmole/hr of the feed
