The roasting of pyrites analyzing 85% FeS2 and 15% gangue utilizes 40% excess air (FeS2 to SO2) supplied at the rate of 358m3/hr at 23 degC, 743 mmHg and 88% RH. A partial analysis of the cinder showed 25.92% FeS2 and 17.83% gangue. Only 65% of the FeS2 gasified is converted to So2, and the rest to SO3. The burner gases are cooled and charged to a converter together with slaked lime containing 75% CaO, 25% MgO. If 850 kg/hr of bisulfite liquor are produced with no oxidation of SO2 to SO3 taking place. Assume all SO2 converted to bisulfite. Calculate: a. kg/hr of lime

Question
The roasting of pyrites analyzing 85% FeS2 and 15% gangue utilizes 40% excess air (FeS2
to SO2) supplied at the rate of 358m3/hr at 23 degC, 743 mmHg and 88% RH. A partial
analysis of the cinder showed 25.92% FeS2 and 17.83% gangue. Only 65% of the FeS2
gasified is converted to So2, and the rest to SO3. The burner gases are cooled and charged to a converter together with slaked lime containing 75% CaO, 25% MgO. If 850 kg/hr of bisulfite liquor are produced with no oxidation of SO2 to SO3 taking place.
Assume all SO2 converted to bisulfite. Calculate:
a. kg/hr of lime
