Problem #1 (30 pts)
Suppose you have a 3-component mixture comprised of ethanol, n-propanol, and n-butanol with mole fractions 0.5, 0.3, and 0.2, respectively, entering a flash drum. The feed rate is 100 and the liquid rate is 20 . A lab technician samples the liquid stream and determines it contains 10mol % ethanol and 20 mol % n-propanol.
a. Perform a Degrees of Freedom analysis and determine if the problem, as stated, is solvable.
b. If solvable as stated, determine the flow rate of the vapor stream and the remaining compositions of the vapor and liquid streams in mole fraction and their respective flow rates in . Otherwise, assume appropriate values to solve.
