Question

A petroleum refinery burns a gas mixture containing C5H12-7%, C4H10-10%, C3H8-16%, C2H6- 9%, CH4-55% and N2-3% at 4.5 bars and 30˚C. The air rate is adjusted such that 15% excess air is used. The ratio of moles CO2 to CO is 20:1 in the flue gas. Calculate the volumetric flow rate of air (in the m3/h at 30˚C and 1 bar pressure) per 100 m3/h of entering fuel gas composition of fuel gas on dry basis​
