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.

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.

Design a Chemical Reactor for the Hydrogenation of Benzene to Cyclohexane:Given the reaction between benzene and hydrogen gas to produce cyclohexane (C6H6 + 3H2 -> C6H12), design a chemical reactor that can convert 900 kg/hr of benzene to cyclohexane, assuming a 90% conversion is desired. The reactor should operate at 300°C and 20 atm, and the hydrogen flow rate is limited to 3000 kg/hr. Determine the reactor type, size, and necessary parameters such as heat transfer, pressure drop, and residence time.

Design a chemical reactor for the exothermic reaction A + B -> C, given the following parameters: - The reaction takes place at a temperature of 500°C- The reaction rate constant is 0.05 L/mol/min- The feed stream contains both A and B in equal molar amounts, with a total flow rate of 100 L/min- The desired product, C, should have a concentration of at least 90% in the reactor effluent stream- The reactor should have a residence time of at least 5 minutes. Determine the type of reactor (batch, plug flow, or continuously-stirred tank) and the dimensions (volume, length, diameter) required to achieve the desired product concentration and residence time, assuming an isothermal and well-mixed reactor.
