A multicomponent mixture containing 27% benzene, 48% cumene and 25% di-siopropyl benzene is fed to the plate column at a rate of 850 kmol/h. The light and heavy key recoveries are 96% and 99%. The details of the relative volatilities are given in below table. If q=1, pressure of the operation takes place at 2 atm and 60°C, calculate: a) The component distribution for each stream (feed, top and bottom products) b) Calculate the minimum reflux ratio

Question

A multicomponent mixture containing 27% benzene, 48% cumene and 25% di-siopropyl
benzene is fed to the plate column at a rate of 850 kmol/h. The light and heavy key recoveries
are 96% and 99%. The details of the relative volatilities are given in below table. If q=1, pressure
of the operation takes place at 2 atm and 60°C, calculate:
a) The component distribution for each stream (feed, top and bottom products)
b) Calculate the minimum reflux ratio
