A mixture of 75.0% propane and 25.0% H2 is burned with 25.0% excess air. Fractional conversions of 90.0% of the propane and 85.0% of the hydrogen are achieved. Of the propane that reacts, 95.0% form CO2 and the rest form CO. Draw the diagram and determine the flue gas (FG) composition (mol%) through an Orsat analysis. Use the elemental balance method.

The following are the details that may help:

1. The fuel contains C3H8 and H2 while air stream contains O2 and N2. This means that the fuel stream (F) is separated from the air stream

2. Aside from the 95% CO2 and (the rest that forms) CO, the flue gas (FG) also contains H2O, O2, and N2

3. The basis can be 100 mol F (fuel)

from mole balance all the values are calculated. Excess air is fed on the basis of complete conversion and complete combustion.
