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 litre.

From the given data, balancing the carbon in both reactant and product Let amount of topgas be x m3 90% * 500 kg = (3.6% * 1000 kg) + (18% * x * 1000* 12)/(44*22.4) kg+ (22% * x * 1000* 28)/(22.4*1000) kg Top gas = x = 414/0.214 = 1934.57 m3
From the given data, balancing the carbon in both reactant and product
Let amount of topgas be x m3
90% * 500 kg = (3.6% * 1000 kg) + (18% * x * 1000* 12)/(44*22.4) kg+ (22% * x * 1000* 28)/(22.4*1000) kg
Top gas = x = 414/0.214 = 1934.57 m3
See lessCorrect answer is in the range of 1927-1937. @Arpita Samal described it best. Thank you. Some peripheral lines related to this topic: Reactions are: C+1/2O2= CO C+O2= CO2
