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.
