Question

Plants in Europe sometimes use the mineral pyrites (containing FeS2 and inerts) as a source of SO2 for the
production of sulphite pulping liquor. Pyrite rock containing 48.0% sulphur is burned completely with dry
air by flash combustion. All the iron forms Fe3O4 in the cinder or the product gas. The gas from such a
furnace is passed through milk of lime (CaO in water) absorbers to produce bisulfite pulping liquor. The
exit gas from the absorber analyzes: SO2 0.7%, O2 2.9%, and N2 96.4%. Calculate the air supplied to the
burner per kg of the pyrites burned.

FeS2 + O2 → Fe3O4 + SO2

The pressure of methane (CH4) and acetylene (C2H2) gas mixture in a container is 70.5 torr. This gas mixture is burned with sufficient O2 and converted to CO2 and H2O. The H2O and excess O2 in the environment are removed and only CO2 is left in the container. Since the pressure of CO2 is 96.4 torr at the same temperature, what is the mole fraction of acetylene in the starting gas mixture?
Air and an unknown amount of methane gas (CH4) are fed into a combustion process. All the water produced during the process was condensed and removed from the bottom of the combustion chamber. The exhaust gases, free of water, exit from the top of the combustion process. An exhaust gas analysis gives 5 mol% O2, 9 mol% CO2, 0.5 mol% CO and the remainder N2. Based on 792 m³/min exhaust gases on a dry basis (SG = 0.3329), determine the percentage of excess oxygen fed to this process.
