A blast furnace charged with hematite containing 90 wt.% Fe₂O₃ produces liquid iron with 3.6 wt.% carbon. Coke containing 90 wt.% carbon is charged at a rate of 500 kg per Metric ton of liquid iron produced. The blast furnace top gas contains (by volume), 22% CO, 18% CO₂, and balance nitrogen. The volume of the blast furnace top gas [in m³ (NTP), rounded off to the nearest integer] is _______.
Given: Assume ideal gas behavior, and molar volume of the gas at NTP is 22.4 liter.
