For a mixture consisting of 45 mol% n-hexane, 25 mol% n-heptane, and 30 mol% n-octane at 1 atm, use a simulation computer program to:
(a) Find the bubble- and dew-point temperatures.
(b) Find the flash temperature, and the compositions and relative amounts of the liquid and vapor products if the mixture is subjected to a flash distillation at 1 atm so that 50 mol% of the feed is vaporized.
(c) Find how much of the octane is taken off as vapor if 90% of the hexane is taken off as vapor. Repeat parts (a) and (b) at 5 atm and 0.5 atm.
