Calculate Fuel Oil Burning In Excess Air

Question

A fuel oil (15% H₂ and 85% C, by weight) is burnt with 50% excess air [basis 100 kg fuel oil]

(a) Calculate the volume of air used.

(b) Calculate the volume percent of N₂ on a dry basis of the resulting flue gas.

(c) How many kg of air per kg of oil will be needed?

(d) Calculate the vapour liquid equilibrium composition of a mixture of benzene and toluene at 84.1°C and 760 mmHg. The saturated vapour pressures of benzene and toluene at 84.1°C are 880 and 330 mmHg respectively.
