Right now, Malampaya is the only sizeable source of natural gas in the Philippines. A certain sample of natural gas from Malampaya analyses 74% methane, 12% ethane, 5.5% propane, 4.7% N2 and 3.8% CO2. A sample of the natural gas is completely burned in a burner using 45% excess air at 30 C, 748 mmHg and 80% relative humidity to produce stack gases at 250 C and 760 mmHg. Calculate a. GCV and NCV of the sample gaseous fuel in MJ/kg b. Orsat Analysis of the stack gas c. m3 stack gas/m3 air d. Dew point of the stack gas in degree C

Question

Right now, Malampaya is the only sizeable source of natural gas in the Philippines. A certain sample of natural gas from Malampaya analyses 74% methane, 12% ethane, 5.5% propane, 4.7% N2 and 3.8% CO2. A sample of the natural gas is completely burned in a burner using 45% excess air at 30 C, 748 mmHg and 80% relative humidity to produce stack gases at 250 C
and 760 mmHg. Calculate

a. GCV and NCV of the sample gaseous fuel in MJ/kg
b. Orsat Analysis of the stack gas
c. m3 stack gas/m3 air
d. Dew point of the stack gas in degree C
