Materials balance
Basis: 1000 kg sinter.
The reduction equations for  and  can be written by using the moles of and  participating in the reaction and taking into account ratio in the exit gas is 2:1. This approach will directly give the moles of products. However, other approaches may also be used

The exit gas amount as determined from Zn vapour balance is 88.186 kg moles.
The amount of exit gas as determined from the stoichiometric reduction equation is equal to 
Difference  is due to excess  and excess in the flue gas. Thus the revised composition of exit gas is
