Crude petroleum oil is generally considered to be formed from animal and vegetable debris accumulating in sea basins or estuaries and decomposed by anaerobic bacteria resulting in black viscous product. A typical elemental analysis shows 80% C, 13% H, 1% N, 3% O and 3% S. During a certain combustion, air supplied is less than the theoretical so that all the O2 is used up. 70% of the C burns to CO2, the rest to CO; the molal ratio of CO to H2 in the exhaust gas is 1:2. Assume that the Sulfur in the fuel burns to SO2 and the Nitrogen combines with the nitrogen from air. Calculate:Orsat analysis of the exhaust gas (Answer: 12.56% CO2, 5.38% CO)% of the theoretical air which is supplied for combustion (70.7%)Equivalence Ratio (1.4)

Given that: the fuel has: C = 80%, H =13% , O = 3% and S= 3%, N = 1% Air supplied is limited and so…

Question

Crude petroleum oil is generally considered to be formed from animal and vegetable debris accumulating in sea basins or estuaries and decomposed by anaerobic bacteria resulting in black viscous product. A typical elemental analysis shows 80% C, 13% H, 1% N, 3% O and 3% S. During a certain combustion, air supplied is less than the theoretical so that all the O₂ is used up. 70% of the C burns to CO₂, the rest to CO; the molal ratio of CO to H₂ in the exhaust gas is 1:2. Assume that the Sulfur in the fuel burns to SO₂ and the Nitrogen combines with the nitrogen from air. Calculate:

Orsat analysis of the exhaust gas (Answer: 12.56% CO₂, 5.38% CO)
% of the theoretical air which is supplied for combustion (70.7%)
Equivalence Ratio (1.4)
