A mixture of 65 mol% methane, 30 mol% hydrogen, and 5 mol% nitrogen is burned to heat a boiler used to produce hot steam. The ratio of CO2 to CO in the exhaust gas is 10:1. If 30% excess air is supplied, determine the concentration of the exhaust gas. Note, all of the methane and hydrogen is consumed.

Methane is completely burned in a boiler with 20% excess air; 30% of the methane converts to CO and the remainder to CO₂. If the barometric pressure is 740 mm Hg and the temperature of the stack gas is 150^oC, what is the partial pressure (mm Hg) of the CO?

5. Determine the required flow rate of methane for an incinerator that will remove 96% of toluene which is present at a mixing ratio of 1000 ppm in the exhaust gas (96% removal means Xi=0.96). Heat losses from the incinerator are 12% and the exit gas temperature is 750 Â°C. The polluted air flow rate is 500 m3 /min at 77 Â°C. Methane and burner air are available at typical ambient temperature (~25 Â°C). Burner air is supplied at a ratio of 14 kg air/kg fuel.

Butane (C4H10) is burned with excess air. The exhaust gas from the combustion is analyzed and has the following composition: 4.5 mole% O2, 73.8 mole% N2, 11.824% H2O, 0.236 mole% C4H10, 8.48 mole% CO2, 1.16 mole% CO. Determine: 1. (8 points) The fractional conversion of C4H10 2. (8 points) The ratio of exhaust produced to C4H10 fed 3. (9 points) The percent excess air fed to the process. Draw a flow chart.
