Question
Plants in Europe sometimes use the mineral pyrites (containing FeS2 and inerts) as a source of SO2 for the
production of sulphite pulping liquor. Pyrite rock containing 48.0% sulphur is burned completely with dry
air by flash combustion. All the iron forms Fe3O4 in the cinder or the product gas. The gas from such a
furnace is passed through milk of lime (CaO in water) absorbers to produce bisulfite pulping liquor. The
exit gas from the absorber analyzes: SO2 0.7%, O2 2.9%, and N2 96.4%. Calculate the air supplied to the
burner per kg of the pyrites burned.
FeS2 + O2 → Fe3O4 + SO2
