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 and the balance reacts in complete combustion. The reaction schemes are shown below:
(1) CH4 + 2O2→ CO2 + 2H2O
(2) CH4 + 3/2O2→ CO + 2H2O
a. Draw a flow chart for this process
b. Calculate the inlet air flow rate in moles/h
c. Calculate the molar flow rate in moles/h and composition of the stack gas on a wet basis

1. Calculate the work (in kJ) when 1.80 moles of methane react with excess oxygen at 425 K: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) 2. Using the technique of the previous problem ΔE was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 5 moles of oxygen gas are consumed and 9 moles of CO2 gas and 4 moles of H2O liquid are...
