Pyrite containing 80% FeS2 and 20% gangue is burned in excess air to produce a gas with a complete analysis of 7.78% SO2, 1.39% O2, 82.06% N2, 4.92% SO3 and 3.85% H20. Analysis of the cinder shows a total sulfur content of 6.46% due to the presence of unburned FeS2 and SO3 absorbed by Fe2O3. Air supplied is at 27°C, 745 mm Hg and saturated with vapor. The burner gases then enter a converter together with 30% excess secondary air (supplied at the same conditions as primary air) based on the complete conversion of all SO2 to SO3. 75% of the SO2 actually burns to SO3. The converter gases enter an absorber and absorbed in acid solution. The waste gases formed has a partial orsat analysis of 0.7% SO2. Calculate per kg of pyrite show the complete analysis of the converter gas

Pyrite containing 80% FeS2 and 20% gangue is burned in excess air to produce a gas with a complete analysis of 7.78% SO2, 1.39% O2, 82.06% N2, 4.92% SO3 and 3.85% H20. Analysis of the cinder shows a total sulfur content of 6.46% due to the presence of unburned FeS2 and SO3 absorbed by Fe2O3. Air supplied is at 27°C, 745 mm Hg and saturated with vapor. The burner gases then enter a converter together with 30% excess secondary air (supplied at the same conditions as primary air) based on the complete conversion of all SO2 to SO3. 75% of the SO2 actually burns to SO3. The converter gases enter an absorber and absorbed in acid solution. The waste gases formed has a partial orsat analysis of 0.7% SO2. Calculate per kg of pyrite
