2. It is desired to produce 10 kg.mol lime from calcinations of CaCO3 (pure) in a rotary kiln. Producer gas of composition 7.2% CO2, 1.6% O2, 16.6% CO and 74.6% N2 is combusted with 20% excess air to obtain the desired temperature in the kiln. The limestone and air are supplied at 298K, whereas producer gas is heated to 900K. Lime is discharged at 1200K and at 500K. Calculate the amount of the producer gas (1atm and 273K).
