Design a distillation column that can effectively separate a mixture containing 50 wt% methanol and 50 wt% water. The column should produce a distillate with no more than 5 wt% methanol and a bottom product with no more than 2 wt% water. The feed rate is 1000 kg/h and the column must operate at atmospheric pressure. Assume that the feed is a saturated liquid and that the methanol-water mixture behaves as an ideal solution. Provide the design specifications for the column, including the number of trays or packing height, diameter, and other necessary specifications.
