9.8 Natural gas stream contains 90 mol% methane and the balance H₂S. The stream flowing at a molar flow rate of 100 mol/min and 25°C enters a combustor chamber. Water in the shell side of the combus- tor is supplied to maintain the combustor exit stream temperature at 25°C. If 50% excess air is used for the combustion, what is the molar flow rate of the gases leaving the combustion process and what is the heat released from the combustor? (-77395 kl/min)

Question
9.8 Natural gas stream contains 90 mol % methane and the balance H₂S. The stream flowing at a molar flow rate of 100 mol/min and 25°C enters a combustor chamber. Water in the shell side of the combus- tor is supplied to maintain the combustor exit stream temperature at 25°C. If 50% excess air is used for the combustion, what is the molar flow rate of the gases leaving the combustion process and what is the heat released from the combustor? (-77,395 kJ/min) The stream is burned completely where the following two reactions take place: CH4 +202 → CO₂ + 2H₂O H₂S +1.50₂ → H₂O + SO₂
