Q2. . Ethylene oxide (C2H40) is produced by catalytic oxidation of ethylene (C2H4). Simultaneously, the combustion of ethylene takes place as an undesired competing reaction. These reactions are given as: 2C2H4 + 02 → 2C2H40 C2H4 + 302 → 2CO2 + 2H20 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 15%, and for every 10 mol/h of ethylene consumed in the reactor, 8 mol/h of ethylene oxide emerge as a product from the reactor. Then, the main product (ethylene oxide) is separated from the reactor's outlet stream. The ethylene and oxygen from the separator are recycled back to the reactor, while the remaining components are discarded. (a) Assume 100 mol/h of reactant is present in the reactor feed stream as a basis of calculation, draw and label the flowchart of the above process. Identify the limiting reactant (5 marks) (b) Perform degree-of-freedom analysis for the reactor using extent of reaction. (3 marks) (C) Determine the values for extent of reaction, 51 and 5 for both reactions. (9 marks) (d) Calculate the molar flow rates of ethylene and oxygen in the fresh feed. (6 marks) (e) Calculate the overall conversion of ethylene. (2 marks) [Total : 25 marks)
