2. 100 moles/h of methane is burned with 100% excess air. The percent conversion of methane is 70%. Of the methane burned, 32% is reacted in partial combustion (reaction 2) and the balance reacts in complete combustion (reaction 1). The reactions are shown below: CH, + 202 → CO2 + 2H,0 3 (1) (2) CH4 +502 → CO + 2H20 a. Draw and label the flow chart for this process. Use variable notation to label the molar flow rate of each components in the streams. b. Calculate the inlet molar flowrate of air. c. Determine the extents of each reaction, §, & $2. d. Calculate the total molar flowrate in moles/h and mole fraction composition of the stack gas on a wet basis (this includes water). e. Calculate the total molar flowrate in moles/h and mole fraction composition of the stack gas on a dry basis (this does not include the water).
