Design a distillation column to separate a mixture of cyclohexane and toluene with a feed composition of 60 mol% cyclohexane and 40 mol% toluene. The distillate product should contain a minimum of 90 mol% cyclohexane and the bottom product should contain a maximum of 10 mol% cyclohexane. You have access to a temperature range of 80-150°C and a pressure range of 1-5 atm. Determine the number of theoretical plates required for this separation and the corresponding reflux ratio.
