Adolescence generally refers to the period from puberty to young adulthood, spanning roughly from ages 12 to 25.

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.

Design a distillation column that separates a mixture of ethanol and water with a 95% ethanol purity and a production rate of 1000 liters per hour. The mixture contains 50% ethanol and 50% water by volume. The distillation column should operate at a pressure of 1 atm and a temperature range of 78-85°C. Assume that the feed enters the column as a saturated liquid and that the overhead product is 90% ethanol, while the bottom product is 5% ethanol. Determine the number of stages required and the reflux ratio for this system.
