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
