A solid ore containing 82 wt% FeS₂ and 18 wt% inert is fed to a furnace. Dry air is fed in 40% excess of the amount theoretically required to oxidize all of the sulfur in the ore to SO3. A pyrite conversion of 85% is obtained, with 40% of FeS₂ converted to form sulfur dioxide and the rest forming sulfur trioxide. Two streams leave the roaster: a gas stream containing SO3, SO2, O2, and N₂, and a solid stream containing uncon- verted pyrite, ferric oxide (Fe₂O3), and inert. Using 100 kg/min of ore as a basis, calculate the rate of Fe₂O3 production (kg/min) in the outlet solid stream, and the total molar flow and composition of the outlet gas stream. The following reactions take place in the furnace: (46.5 kg) FeS₂ (s) + 15 O₂ (g) → Fe₂O3(s) + 4SO3 (g) 2 11 O₂ (g) → Fe₂O3 (s) + 4 SO₂ (g) 2 2FeS₂ (s) +-

5.10 A solid ore containing 82 wt% FeS₂ and 18 wt% inert is fed to a furnace. Dry air is fed in 40% excess of the amount theoretically required to oxidize all of the sulfur in the ore to SO3. A pyrite conversion of 85% is obtained, with 40% of FeS₂ converted to form sulfur dioxide and the rest forming sulfur trioxide. Two streams leave the roaster: a gas stream containing SO3, SO₂, O₂, and N₂, and a solid stream containing uncon- verted pyrite, ferric oxide (Fe₂O3), and inert. Using 100 kg/min of ore as a basis, calculate the rate of Fe₂O3 production (kg/min) in the outlet solid stream, and the total molar flow and composition of the outlet gas stream. The following reactions take place in the furnace: (46.5 kg) 15 FeS₂ (s) + O₂ (g) → Fe₂O3(s) + 4 SO3 (g) 2 11 (s) + ¹/2 ( 2FeS₂ (s) + (g) → Fe₂O3 (s) + 4 SO₂ (g)
