Question

. (5pt) Ethylene oxide is produced by the catalytic oxidation of cthylenc C3H4 + O2 → C2H40 An undesired competing reaction is the combustion of ethylene CO2 + H2O C2H4 + O2 The feed to the reactor contains 4 moles of ethylene per mole of oxygen, while the oxygen contains 0.4% inerts. The single pass conversion of ethylene is 15% and for every 100 moles of ethylene consumed in the reactor, 80 moles of ethylene oxide emerges in the reactor products. A multiple-unit process is used to separate the products: ethylene, oxygen, and inerts are recycled to the reactor, ethylene oxide is sold as a product, and carbon dioxide and water are discarded. A purge stream is needed to remove the same amount of inerts from the system as the amount of inerts that enters the system. The reactor effluent contains 2.06% inerts. Base your calculations on an exiting stream of cthylene oxide that amounts to 225 kmol/hr. a Draw and label a flow diagram. b) Calculate the molar flow rates of ethylene oxygen, and inerts in the fresh feed, the molar flow rates of the recycle stream, the molar ow rate carbon dioxide and water exiting the system, and the molar flow rates of thc ar 2. (5pt) A mixture of propane and butane is burned with pure oxygen. The combustion products contain 47.4 mole'% H2O. After all the water is removed from the combustion products, the residual gas is found to contain 69.4 mole% CO2 and the balance what is the mole percent of propane in the fuel
