Mixture of methane and hydrogen is burned in a furnace. The air is fed into furnace as source of oxygen. The stack gas is analyzed to be composed of 87.18 mol% N2, 9.81 mol% CO2, 3.01 mol% O2. The humidity measurement shows that the mole fraction of H2O in the stack gas is 17.16%.

a. Calculate the molar composition of stack gas on a wet basis

b. Draw and label a flowchart of the process

c. What is the molar ratio of methane and hydrogen in the feeding gas

d. What is the molar ratio of feeding gas and air (assume air is composed of 79% N2 and 21% O2)

Methane gas is burned completely with 30% excess air in a furnace operating at one atmosphere. Both the methane and air enter the furnace at 40ºC saturated with water vapor. The flue gas (furnace exhaust) leaves the furnace at 1000ºC. The flue gas then passes through a heat exchanger and emerges at 60ºC. If 260 mole/sec of methane fed to the furnace, how much heat is lost from the furnace, and how much heat is transferred in the heat exchanger?...

A fuel gas containing 75.0 mole% methane and the balance ethane is burned completely with 35.0% excess air. The stack gas leaves the furnace at 800.0°C and is cooled to 350.0°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. Take as a basis 100.0 mol of the fuel gas fed to the furnace. The amounts of each of the...
