Molar flow ammonia oxidation

P11-7b The oxidation of ammonia is to be carried out over platinum gauze. The molar flow rate of ammonia is 10 mol/min at a temperature of 500 K and a pressure of 202.6 kPa. Is one 250-mesh screen 10 cm in diameter sufficient to achieve 60% conversion The wire diameter is 0.044 mm. Assume 25% excess air, and ignore the effects of volume changes on the Reynolds number. 

The overall objective is to produce triethanolamine, which is featured in the third reaction. Which of the following alternatives is more desirable a stoichiometric (1 1) feed of ethylene oxide and ammonia enters the reactor or a 3 1 molar ratio of ethylene oxide to ammonia enters the reactor Provide support for your answer by calculating the reactor volume in liters and the outlet molar flow rate of triethanolamine that correspond to your design. 

Finally, the mole fraction of component i is written as its molar flow rate divided by the total molar flow rate. The differential mass balance is written for each component in the mixture A = ethylene oxide, B = ammonia, C = monoethanolamine, D = diethanolamine and E = triethanolamine. The matrix of stoichiometric coefficients is summarized as follows for five components that participate in three independent chemical reactions ... 

The feed stream contains a 3 1 molar flow rate ratio of ethylene oxide to ammonia. 

Ammonia is burned to produce nitric oxide. The fractional conversion of the limiting reactant is 0.5. The inlet molar flow rates of NH3 and O2 are 5 kmol/h each. The operating temperature and pressure are 25°C and 1 atm. Calculate the exit components molar flow rates. Assume that the reactor is operating adiabatically.
