volume percentage
The composition of a gas derived by the gasification of coal is, volume percentage: carbon dioxide 4, carbon monoxide 16, hydrogen 50, methane 15, ethane 3,benzene 2, balance nitrogen. If the gas is burnt in a furnace with 20% excess air, calculate:
(a) the amount of air required per 100 kmol of gas.
(b) The amount of flue gas produced per 100 kmol of gas.
(c) the composition of the flue gases, on a dry basis.
