A feed rate of about 7.74kmol/h of equimolar mixture of methyl-ethyl ketone (MEK) (1) and n-hexane (2) is fed into a double flash distillation columns. Both columns are maintained at 55oC albeit at different operating pressure . The first column is at 0.395 atm while the second one is at 0.296 atm. Using Raoult’s Law and the Antoine constants, calculate the following a.The composition and amount of the resulting equilibrium phases at the first flash column b. The composition and amount of the resulting equilibrium phases at the second column c. What percentage of the MEK in the initial feed entering the first flash distiller ends up in the liquid exiting the second flash distiller d. Which assumption that you made in solving this problem would you characterize as least valid and why?
