Producer gas has the following composition by volume: O2 . The oxygen fed from the air and the producer gas is 20% in excess of 68.0 1.2507 2CO + O2 2CO2 The oxygen is from the air whose volumetric composition is assumed to be 80% N2 % Density, kg/m3 The gas is burned with oxygen according to the following equation: CO2 3.5 1.9768 the amount required for complete combustion. The combustion is 98% complete. N2 CO 28.0 1.2501 0.5 1.4289 and 20% O2 Carry out total material balance for this process based on 100kg of gas burned.​
