A natural gas contains 96 wt% CH4 and the balance C2H6. Five hundred cubic meters per hour of this gas at 40 oC and 1.1 bar is to be burned with 30% excess air. The air flow meter is calibrated to read the volumetric flow rate at standard temperature and pressure. What should be the meter read (in SCMH) when the flow rate is set to the desired value?

A natural gas containing 82 mole% CH, and the balance C2H6 is used as a fuel to generate steam in an industrial plant (Figure 2). The natural gas is fed into a furnace at 25°C and burned at a rate of 10.000 mol/hr with 20% excess air. The heat transferred from the furnace is used to convert a liquid feed water at 25 °C into a saturated steam at 30 bar. During the combustion of natural gas, all the CH,...

Problem: Bapco needs to burn natural-gas fuel that contains 75 mol% methane, 15 mol% ethane, and 10 mol% nitrogen. The following two reactions takes place: CH4(g) 20209) CO2(0) 2H2o) C2H6 (g) + 3.502(g) 2C02(g)3H20 (g) a) What is the standard heat of combustion (kJ/mol) of the fuel at 25 oC with water(g) as a product b) The fuel is supplied to a furnace with 60% excess air, both entering at 250C. The products leave at 600°C. If the combustion is...

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...
