- An equimolar vapor mixture of n-pentane and n-hexane at 100 °C and 1 atm is fed at a rate of 150 SCMH to a condenser at 40 °C where there is partial condensation of the mixture. 60% of the initial feed is condensed.
- Do a degree of freedom analysis to demonstrate that you can solve for all molar flow rates, then calculate them.
- How much heat must be transferred from the mixture in the condensation process?

The vapor-liquid equilibrium for n-pentane and n-hexane at 1 ATM is well approximated using a constant relative volatility of 2.95. CMO is valid. For all the problems, the feed stream is flowing at 80 mol/s and contains 45 mol% n-pentane, the feed is a saturated liquid (q = 1) at the column pressure, the distillate is 95 mol% n-pentane, and the bottoms is 10 mol% n-pentane. In this problem, you should analyze the column graphically using the McCabe-Thiele Method a....
