A sulfur burner, burning sulfur of 98% purity with dry air, discharged gas at 1300°F containing 16% SO2, 5% O2, and 79% N2. Both the sulfur and the air supplied are at 80°F. The heat of combustion of sulfur to SO2 is 127690 BTU/lbmole at 25°C. The burner gas is mixed with more dry air (secondary air) and passed through a converter. Analysis of the converter gas shows 4.2% SO2, 7.5% O2 and 88.3% N2. An absorber subsequently removes 95% of the SO3 in the converter gas by absorbing it in 97% H2SO4 to produce 100% H2SO4 solution. No SO3 is formed in the absorber. a. Calculate the volume of secondary air supplied at 80°F and 735 mmHg per 100 lbs impure sulfur entering. b. How many pounds of 97% H2SO4 solution must be supplied per mole of SO3-free converter gas?
