A chemical plant has a mixture of ethanol and water with a known composition. The plant wants to separate the mixture using a distillation column. As a chemistry student, design a feasible distillation column that can effectively separate the mixture with the given composition. You need to specify the height, diameter, number of trays, reflux ratio, and other necessary parameters needed for designing the column. You are also required to provide an explanation for the choice of each parameter.
