The natural gas that is fed to your stove has the following molar composition: 

88% methane, 4% ethane, 2% propane, 2% iso-butane (C4H10), 3% nitrogen, 1% CO2 Assume that the gas is burned with 10% excess air under the following conditions: 

95% methane conversion,90% ethane conversion 

the propane mole fraction in the outlet is 0.001 

the CO2 to CO selectivity is 4

all the iso-butane is totally burned 

a)Draw and clearly label a flowsheet for the stove burner.
b)Write balanced equations for all possible combustion reactions that can take place. 

c)Assuming a basis of 100 gmol/min of gas entering the stove, determine the inlet air flow rate required. 

d)Determine the outlet gas composition by setting up a series of balance equations and solving them with Matlab or Mathematica.
