Bisulfite liquor having 81% FeS2, in a burner together with excess air. The burner gas, 5.84% SO2, 9.72% 02 and 84.44% N2, enters the absorption tower charged with lime, 82% CaQ. 16% MgO and 2% inerts. The liquor produced hold 7.05% SO2, 1.15% of it is "free" and the rest as bisulfites. The cinder exiting the burner contains 8.29% FeS2 and 3.81% SO3. Assume that no conversion takes place in the tower and only O2 and N2 is in the waste gas. a) What is the kg pyrites/kmol of burner gas? b) What is the kg of SO3 in the cinder per kmol of burner gas? c) What is the kg of bisulfite liquor per kg of pyrite?
