What is LNG?

• Liquid Nitrogen Gas

• Liquified Natural Gas

• Light Natural Gas

• Liquid Neon Gas

At what temperature is natural gas typically liquefied to form LNG?

• -100°C

• -160°C

• 0°C

• -200°C

Which primary component makes up most of natural gas?

• Propane

• Butane

• Methane

• Ethane

Where does LNG come from?

• Derived directly from oil

• Produced from propane

• Extracted from natural gas reservoirs

• Obtained from underwater sources only

Why is LNG preferred for long-distance transportation?

• It is lighter than natural gas

• It requires no special storage

• Its volume is reduced, making transportation more practical

• It does not require any processing

How is LNG transported over long distances?

• Through pipelines

• In cryogenic storage tanks on specialized LNG carriers

• In regular cargo ships

• Through tunnels

What is the primary design requirement for materials in cryogenic LNG tanks?

• High thermal resistance

• High resistance to corrosion only

• High strength and low brittleness at extremely low temperatures

• Resistance to high temperatures
