Please read the question carefully. Use the McCabe-Thiele method

Four hundred and fifty lbmol/h (204 kmol/h) of a mixture of 60mol% benzene (Light Key) and 40mol% toluene (Heavy Key) is to be separated into a liquid distillate and a liquid bottoms product of 98mol% and 2mol% benzene, respectively. The feed enters the column with a molar present vaporization equal to the distillate-to-feed ratio. (1) Use the McCabe-Thiele method to compute at 1atm (101.3 kPa): (a) minimum number of stages, Nmin, (b) minimum reflux ratio, Rmin, and (c) number of equilibrium stages, N, for R/Rmin=1.4, and the optimal feed-stage location. (2) Determine packed bed height for distillation of a mixture of benzene and toluene using HETP method.
