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:...
