Natural Gas Concepts and Applications

Natural gas, primarily methane, is formed from ancient organisms under heat and pressure. It is found in reservoirs and categorized as dry or wet gas. Extraction methods vary for conventional and unconventional types. Once extracted, it is processed to remove impurities and transported via pipelines. Natural gas is used for heating, electricity, and as a feedstock. It emits fewer greenhouse gases than coal but still contributes to CO2 emissions. Methane leaks during extraction pose environmental and safety risks.

What is the primary component of natural gas?

• Propane

• Methane

• Ethane

• Butane

How is natural gas trapped underground?

• By a layer of oil

• By a layer of sand

• By a layer of water

• By a cap rock

What distinguishes dry gas from wet gas?

• Wet gas contains only methane

• Dry gas contains mostly methane

• Wet gas is free of hydrocarbons

• Dry gas contains ethane and butane

Which of the following is an unconventional form of natural gas?

• Shale gas

• As a feedstock for fertilizers

How does natural gas compare to coal in terms of carbon emissions when used for electricity?

• Emits no carbon

• Emits the same amount

• Emits half as much

• Emits twice as much

Why are natural gas leaks dangerous?

• They are easy to detect

• They are non-toxic
