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.

Calculate the standard enthalpy change for the complete combustion of methane gas (CH4(g)) at constant pressure, given the balanced equation: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l). The standard enthalpies of formation of CO2(g), H2O(l), and CH4(g) are -393.5 kJ/mol, -285.8 kJ/mol, and -74.8 kJ/mol, respectively.
