A tray tower distils 204kmol/h of a binary mixture of 60% benzene and 40% toluene. Liquid distillate contains 95% of benzene and the bottom product contains 5% benzene. The feed is preheated so it enters the column with a molar percent vaporization equal to distillate to feed ratio. Use McCabe-Thiele method to find: a) The minimum number of theoretical stages. Compare the result with the Fenske equation (=2.5) b) The minimum reflux ratio c) The number of equilibrium stages given the R/Rmin=1.3 Equilibrium data
