A local plate glass factory burns natural gas in its glass furnaces. To ensure complete combustion of the fuel, 25% excess air is provided. While the composition of natural gas is variable, the natural gas found in Ohio has the following mole% composition: 93.5% methane, 4.24% ethane, 1.11% N2, and 1.15% CO2. Their plant produces 15 tons per day of plate glass using the float method. Melting this glass requires 4.3 million BTUs/day provided by 116 SCM of natural gas burned/day.
5a: How many moles of natural gas are consumed per day by the furnace?
5b: How many moles of each of natural gasâ components are injected into the burners per day?
-Methane
-Ethane
-Nitrogren
-Carbon Dioxide
5c: Assuming that the fuel in the natural gas is completely combusted, write the stoichiometric reaction equations for the methane and ethane.
5d: In addition to the fuel combustion products, 8.8 lbs. of NO/ton of glass is produced by the combustion process, consuming some of the nitrogen in the air. Since NO is a pollutant, it should not be considered in the excess air calculations. What is the flowrate in kgmol/day of each component of the flue gas?
