20 A mixture of 80 mole% ethane (C2H) and 20 mole% hydrogen (H2) flowing at rate of 200 mol/h is bumed with 30% excess air. 92% fractional conversions of C,H, and 85% of H, are achieved with below reactions. C2H6+ (reaction 1) + 2 CO2 + 3 H20 2 H2 + O2 2 H20 (reaction 2) Beside, the below undesired reaction also got carried out in the same reactor resulting to produce Co. Of the C2H6 that reacts, 85% formed CO2 and the balance reacted to form Co. Process flowchart is given. Solve for the following: 5 C2H6+ (undesired reaction) 2CO + 3H20 202 2 7-200 (mol/h) 0,8 02 n (mol/h) 1 (mol-CH./h) - (no-Hy h) por 0.21 1 (mol-C0y/h) ne (mol-CO/h) -0.79 ns (mol-H.0/h) no (mol-Oh) 1 (mol-Ny/h) a) Stoichiometric moles of O2 required b) Determine amount of air fed to the process (Hair) c) Prove that CzHg is the limiting reactant d) Perform the degree-of-freedom analysis, based on molecular balance method, and comment of your results e) Calculate molar flowrates of C:H: (m), H2 (n2), CO2 (13) and CO (14) leaving the reactor.
