We desire t. o separate a feed of 75 mole % ethanol and 25 mole % propanol that is a saturated vapor at 556 moles/hr. distillate composition should be 99 mole % ethanol and bottoms 10 mole % ethanol. a partial reboiler and a total condens. er are used. reflux is a saturated liquid, and constant molal overflow can be assumed. the system has a constant relative volatility of 2.1, and ethanol is more volatile. boilup ratio v /b is 2.0. we desire to find the liquid composition leaving the second stage above the reboiler. note that the reboiler acts as an equilibrium contact. solve this problem both analytically and graphically.
