Mixture of methane and hydrogen is burned in a furnace. The air is fed into furnace as source of oxygen. The stack gas is analyzed to be composed of 87.18 mol% N2, 9.81 mol% CO2, 3.01 mol% O2. The humidity measurement shows that the mole fraction of H2O in the stack gas is 17.16%.
a. Calculate the molar composition of stack gas on a wet basis
b. Draw and label a flowchart of the process
c. What is the molar ratio of methane and hydrogen in the feeding gas
d. What is the molar ratio of feeding gas and air (assume air is composed of 79% N2 and 21% O2)
