Extracted text: Natural gas stream contains 90 mol% methane and the balance H,S. 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: 9.8 CH4 + 202 СО2 + 2H,0 -> H,S +1.502 → H2O+ SO2
