A family-owned dairy is trying to reduce its carbon footprint. They typically burn propane as a heat source to pasteurize their products, but one of their new engineers has the idea to add hydrogen to the propane. The hydrogen could be obtained by electrolysis of water from green power supplied by covering the roof of the dairy with solar panels. The output of the solar panels would be more than needed for the electrical requirements of the dairy, so the extra electrical capacity could be used to make hydrogen. The propane/hydrogen mixture (75 mol% propane) is fed to a burner with 25% excess air. Ninety-five percent of the propane that reacts undergoes complete combustion and the rest partial combustion. Ninety percent of the propane and 85% of the hydrogen are consumed in the process. Calculate the composition of the exhaust. Report the CO concentration in ppm and the other concentrations as mole fractions on a dry basis.
