You have been employed as a chemical engineer in a chemical plant that producing ethylene oxide in Pengerang, Johor. Your first job is to design the catalytic oxidation process of ethylene to produce the Ethylene oxide. There are two chemical reactions take place in the reactor as shown below: 2C2H4+O2C2H4+3O22C2H4O2CO2+2H2O The feed to the reactor (not the fresh feed to the process) contains 3 moles of ethylene per mole of oxygen. The single-pass conversion of ethylene is 20%, and for every 100 moles of ethylene consumed in the reactor, 90 moles of ethylene oxide emerge in the reactor products. A multipleunit process is used to separate the products: ethylene and oxygen are recycled to the reactor, ethylene oxide is sold as a product, and carbon dioxide and water are discarded. a. Draw a complete process flow diagram (labelled appropriately) and perform a complete degree of freedom analysis (10 marks) b. Determine the molar flow rates of ethylene and oxygen in the fresh feed (10 marks) c. Determine the production rate of ethylene oxide (5marks) d. Determine the feed the overall conversion of ethylene. (5 marks) e. Determine the molar flow rates of ethylene and oxygen in the fresh feed needed to produce 1 ton per hour of ethylene oxide
