burner gas with an Orsat analysis of 5.84% SO2, 9.72% O2 and 84.44% N2. Analysis of the cinder shows 8.29 % unburned FeS2 and 3.81% SOs. The gases from the burner are cooled and made to come into contact with Milk of Lime in an absorption tower. The dolomitic lime used is 82% CaO, 16% MgO and 2% inerts. The bisulfite liquor produced contains 7.05% total SO2 of which 1.15% is "free" and the rest 5.9% being present as bisulfites. An analysis of the dry waste gas shows that it contains only O2 and N2. Assuming no further oxidation of SO2 to SO3 and formation of H;SO. in the tower. alculate: a. kg pyrites/ kmol of BG b. kg of SO, in cinder/ kmol of BG c. kg of bisulfite liquor/ kg of pyrite d. kg of lime/ kmol of BG e. kg of water for slaking/ kmol of BG

CHEMICAL CALCULATION

2. Pyrites analyzing 81% FeS2 and 19% gangue is burned in excess air to produce a burner gas with an Orsat analysis of 5.84% SO2, 9.72% O2 and 84.44% N2. Analysis of the cinder shows 8.29 % unburned FeS2 and 3.81% SO3. The gases from the burner are cooled and made to come into contact with Milk of Lime in an absorption tower. The dolomitic lime used is 82% CaO, 16% Mgo and 2% inerts. The bisulfite liquor produced contains 7.05% total SO2 of which 1.15% is "free" and the rest 5.9% being present as bisulfites. An analysis of the dry waste gas shows that it contains only O2 and N2. Assuming no further oxidation of SO2 to SOs and formation of H;SO. in the tower. Calculate: a. kg pyrites/ kmol of BG b. kg of SO3 in cinder/ kmol of BG c. kg of bisulfite liquor/ kg of pyrite d. kg of lime/ kmol of BG e. kg of water for slaking/ kmol of BG
