4. A CH4 – N2 fuel gas mixture is burned with air (80 mo% 02 and 20%) in a continuous
steady-state combustion reactor to yield a mixture of oxygen, nitrogen carbon monoxide,
carbon dioxide, and water. The combustion reactions taking place are:
(1)
CH4 + 202
CO2 + 2H20 *complete combustion, the desired reaction
CH4 +02 → CÓ + 2H20 *partial combustion, the side reaction
The outlet flue gas is flowing at a rate of 100.0 mol/min and is composed of 6.0 % CO2,
1.0% CO, 3.5% O2, 75.5% N2, and 14.0 mol% H2O. A flow chart of the process is shown
below, with the following notation: CO=C02, CO=CO, 0x=0, N=N and H20=W , citu=M
