Chemistry

3. Natural gas is a mixture of hydrocarbons and recentdevelopments in directional drilling and hydraulic stimulation hasseen that the majority of natural gas is now produced from shalegases. These gases may contain higher proportions of higheralkanes. In order for these gases to be used via the pipeline, theymust meet certain pipeline quality standards. These standards areeven stricter when the natural gas is to be used by natural gasvehicles. Suppose natural gas from a shale well enters yourfurnace. The pressure and temperature of the mixture are 17 °C and100 kPa. A molar analysis shows the gas is 80% methane, 10% ethane,and 10% propane. Determine the following:

a.) Mass fraction of each component (10 points)

b.) The partial pressure of each component (10 points)

c.) The mass flow rate in kg/s for a volumetric flowrate of 1m3/sec (10 points)
