A mixture of 75mol% propane and 25mol% hydrogen is burend with 25% excess air. Fraclional conversion of 90% of the propane and 85% of the hydrogen are achieved; of the propane that reacts, 95% reacts to form CO2 and the balance reacts to form CO. The hor combustion product gas passes through a boiler in which heat transferred from the gas converts boiler feedwater into steam. (a) Draw and label the process flowchart and perform the degree-of-freedom analysis. (b) Calculate the molar composition of the hot combustion product gas on both a wet and a dry basis. (c) Calculate the concentration of CO(ppm) in the stack gas since it is a pollutant
