Raw sulfur containing 83% pure S is burned together with 30% excess air (S to SO2). An analysis of the cinder shows 20% unburned sulfur and 80% inerts. Air is supplied saturated at 30 °C and 750 mmHg. The gases from the burner gas enter a converter where SO2 is converted to SO3. A partial Orsat analysis of the converter gas shows 1.37% SO2, The gases from the converter enter an absorber where H2SO4 solution is formed. Waste gas leaves the absorber containing 0.55% SO2, 11.99 % O2, and 87.46% N2 On a basis of 100 kg of raw S charged, calculate: a) complete analysis of burner gas; b) weight of 60% H2SO4, entering the absorber needed to produce 87% H2SO4 c) weight of 14% oleum if the absorbing acid is 94% H2SO4 3.
