A gaseous fuel containing methane and ethane is burned with excess air. The fuel enters the furnace at 25°C
and 1 atm, and the air enters at 200°C and 1 atm. The stack gas leaves the furnace at 800°C and 1 atm and
contains 5.32 mole% CO2, 1.60% CO, 7.32% O₂, 12.24% H₂O, and the balance ₂.
1. Calculate the molar percentages of methane and ethane in the fuel gas and the percentage excess air fed
to the reactor.
2. Calculate the heat (kJ) transferred from the reactor per cubic meter of fuel gas fed.
3. A proposal has been made to lower the feed rate of air to the furnace. State advantages and a drawback of
doing so.
(5) The emissions from a manufacturing process contain gaseous pollutant that cause odors and fumes.
The company plans to incinerate the 5,000 acfm exhaust stream. Estimate the volumetric (standard)
flowrate of natural gas fuel required to increase the waste gas stream temperature from the initial 80°F
to the required temperature of 2500°F. Energy (enthalpy) is transferred from the fuel to the gas. Neglect
any possible heat losses in this process. The average net heating value of natural gas is 850 - 1050
Btu/std-ft. Include a diagram of the scenario.
0.1 g of a sample of coal was used in a bomb calorimeter for the determination of
calorific value. The ash formed was extracted with acid and the acid extract was heated with
BaCl2 solution and a precipitate of BaSO4 was obtained. The precipitate was filtered, dried
and weighed. The weight of precipitate was found to be 0.01 g. Calculate the percentage of
sulfur in the coal sample.

The emissions are caused by the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide. This process known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns. A large cement manufacturer uses a mix of coal, natural gas, and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of energy: • 250 lbs CO2/MMBtu • 5 lbs CH4/MMBtu • 0.36 lbs N2O/MMBtu Process carbon emissions from the calcination process produce 925 lbs of carbon dioxide per metric ton of cement.
