Iron pyrite fines containing 90% FeS2 and 10% gangue are burned in a Herreshoff Burner supplied at 250 pounds per hour. The air is supplied 20% excess (to SO3). Assuming there is no SO3 formed in the burner. There is also no unburnt sulfur in the cinder and 90% conversion occurs in the converter. 80% H2SO4 uses in absorption tower as absorbing acid. There is 100% concentrated acid that is produced. Establish: 100lbs of iron pyrites a. Burner gas analysis? b. Converter gas analysis in orsat? c. Assuming that the waste gas analyzes 0.17889% SO2, 4.1443%O2 and 96% N2. How much absorbing acid should be charged in the tower per day?
