1. 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 a 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 of the O2 is used up. 70% of the C burns to CO2, the rest to CO; the molal ration of CO to H2 in the exhaust gas is 1:2. Calculate: (a) Orsat analysis of the exhaust gas (12.56% CO2, 5.38% CO) (b) % of the theoretical air which is supplied for combustion (70,7%)

1. 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 a 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 of the O2 is used up. 70%
of the C burns to CO2, the rest to CO; the molal ration of CO to H2 in the exhaust gas is 1:2.
Calculate:
(a) Orsat analysis of the exhaust gas (12.56% CO2, 5.38% CO)
(b) % of the theoretical air which is supplied for combustion (70,7%)
