In a blast furnace hematite is reduced to a sponge iron by carbon monoxide. The
requirement for reduction is an excess of CO equation.
Fe2O3 + xCO = 2Fe + 3CO + (x β 3)CO
The volume ratio of the gas is CO/CO2 = 1.8
The furnace produces 800 tons Fe per 24 hours.
Coke contains 90%C and produces 2C + O2 = 2CO
Calculate:
a) The number of moles of MCO which is x
b) Coke consumption per ton Fe
c) The true CO/CO2 ratio if 200 kg of CaCO3 is added for each of tons of Fe2O3
reactions CaCO3 = CaO + CO2
