A student is asked to design a distillation column for the separation of a mixture consisting of ethanol and water. The student has to determine the number of theoretical plates required for the column to achieve a product concentration of 95% ethanol, given the feed mixture contains 25% ethanol and 75% water. The student also needs to calculate the amount of steam required for the reboiler to operate at a reflux ratio of 3.5, assuming the total condenser efficiency is 100%.
