At 330 K the vapor pressure of pure n-pentane is 1.92 atm and the vapor pressure of pure n-octane is 0.07 atm. If 330K is the normal boiling point for a solution of these two substances, what will the mole fractions of each substance be in that solution? [If you can't figure out how to do this mathematically, you can estimate from the plot..... for reduced credit.] Octane+Pentane Pvaps at 330K po Pentane P (atm) Ptot Pv Pent Pv Oct...

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....
A liquid feed at 4.0 atm absolute pressure is fed to a distillation tower. The feed composition is as follows: n-butane (40%), n-pentane (25%), n-hexane (20%), n-heptane (15%) Calculate the bubble-point and the composition of the vapor in equilibrium with the liquid. Equilibrium K values for this system are plotted in the chart given below. So the professor used some symbols that were not clearly covered in class. if you could please solve using symbols in the image below, and...
