A chemical mixture containing 30% ethanol and 70% water needs to be separated using a distillation column. The feed rate is 1000 kg/hr and the desired purity for both products is 99%. The distillation column has 20 theoretical trays, and the reflux ratio is 2.5. Determine the number of trays required to achieve the desired purity for both products.
