Question
2.82 A gaseous fuel consisting of a mixture of methane (CH4) and ethane
(C2H6) is fed into a burner in a proportion of 1 mol of fuel per 20 mol of
air. The following reactions are believed to take place in the reactor:
CH4 + 202
CO2 + 2H2O
2СН6 + 702
4СО2 + 6H20
An analysis of the flue gas (dry basis) indicates that it consists of 83.7% N2,
7.01% CO2, 9.15% O2, and 0.14% methane (percent mole). Calculate:
a. The composition of the fuel
b. The conversion of oxygen
c. The conversion of methane
d. The conversion of ethane
e. The excess amount of air used
