Design a chemical reactor for the production of 500 kg/day of ethylene oxide through the oxidation of ethylene with oxygen in the presence of a silver catalyst. The reactor should achieve a conversion of 85% with a selectivity of 95% towards ethylene oxide, while operating at 3 atm and a reactor temperature range of 200-250°C. The feed stream consists of 15% ethylene, 5% oxygen, and the rest is nitrogen. Determine the appropriate reactor type, size, and operating conditions to achieve these specifications.

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.
