2. Natural gas containing a mixture of methane, ethane, propane, and butane is burned in a furnace with excess air. One hundred kmol/h of a gas containing 94.4 mole% methane, 3.40% ethane, 0.60% propane, and 0.50% butane is to be burned with 17% excess air. a) Calculate the molar flow rate of the air. b) Now instead of using numerical values, we will work the problem by deriving an equation. Define the following variables: i.molar flow of the fuel gas:...

A fuel gas that contains
mole% methane and the balance ethane is burned completely with
pure oxygen at
°C, and the products are cooled to
°C.
suppose that the combustion takes place in a constant-volume
batch reactor. Take
mol as a basis of calculation of the fuel gas charged into the
reactor and assume any percent excess oxygen,

A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...
