A chemical engineering company has a mixture of ethanol and water with a concentration of 30% ethanol to separate using a distillation column. The company needs to obtain a concentration of 80% ethanol in the distillate at a reflux ratio of 3. Calculate the number of theoretical plates required in the column for the separation, assuming no vapor or liquid bypass, and that the minimum vapor velocity is maintained.
