Question

A sample of natural gas containing 80% methane (CH4) and rest nitrogen (N2) is burnt with 20% excess air. With 80% of the combustibles producing CO2 and the remainder going to CO, the Orsat analysis in volume percent is_________________?

Answer 1

A. CO2 : 6.26, CO : 1.56, O2 : 3.91, H2O :15.66, N2 : 72.60
B. CO2 : 7.42, CO : 1.86, O2 : 4.64, N2:86.02
C. CO2 : 6.39, CO : 1.60, O2 : 3.99, H2O:25.96, N2:72.06
D. CO2 : 7.60, CO : 1.90, O2 : 4.75, N2 : 85.74

Correct Answer: CO2 : 7.42, CO : 1.86, O2 : 4.64, N2:86.02 ✔
