Design a chemical reactor for the production of ethylene oxide through the direct oxidation of ethylene. The reactor should have a production rate of 100 tons per day and maintain a constant temperature of 250°C. Assume a feed composition of 90% ethylene and 10% oxygen. The reactor should also have a conversion efficiency of at least 95%. Compute the necessary reactor volume and the optimal flow rate of ethylene and oxygen to achieve the desired production rate and conversion efficiency.
