Natural Gas Unlocking the Low Carbon Future


Quiz Questions

1. Natural gas has long been the fuel of choice because of the efficiency of this form of energy distribution, gas’s flexibility and controllability in use, and on account of its low emissions of CO2 and low levels of pollutants.
True
False
2. Natural gas is highly efficient. About 90 percent of the natural gas produced is delivered to customers as useful energy. In contrast, only about 27 percent of the energy converted to electricity reaches consumers.
True
False
3. ____________________ serves to illustrate that the conversion of primary energy forms to electricity is of major importance.
Figure 2.1
Figure 2.2
4. Natural gas with its low carbon and high hydrogen content as well as its global reach is a prime candidate for throwing a bridge to this lower carbon future.
True
False
5. A natural gas chain starts with a gas field contained in a geological structure such as a sandstone perhaps several thousand meters underground.
True
False
6. The gas chain typically starts at the burner tip, motor or turbine at the site of the consumer.
True
False
7. The main constituent of ______________________ is the methane molecule which contains four hydrogen atoms clustered around one carbon atom.
Natural gas
Ethane gas
8. Methane in combination with water is used extensively in the chemical industry to make the so-called synthesis gas.
True
False
9. Power generation capacity is represented in ___________________________.
Figure 3.14
Figure 3.15
10. Gas flaring is not a large problem in the natural gas industry itself, but is rather a byproduct of the production in the oil industry.
True
False
11. Carbon dioxide captured from natural gas has an important place in climate mitigation even if the amount of this CO2-contamination does not amount to great tonnages.
True
False
12. The limitation or elimination of flaring, venting and fugitive emissions of methane from the oil industry is one important area where the gas industry can assist another branch of industry in climate change mitigation.
True
False
