In a chemical plant 240kmol combustible gas mixture with 20% excess air is fed into a burner unit. The gas product from the burner is cooled to remove all the water to yield a dry gas. The Orsat analysis of this flue gas shows that for every 2kmol CO2 produced; 3kmol CO is produced. (Ratio of CO2 /CO produced is 2/3) Analysis of the combustible gas mixture fed into the burner: 60% CH4, 20% C2H4, 10% CO, 5% O2 , 5%N2
