Liquefied Natural Gas (LNG)
Liquefied Natural Gas (LNG) is natural gas that has been cooled to a liquid state for ease of storage and transport.
Characteristics
Composition: Primarily methane (CH₄), with small amounts of ethane, propane, and other hydrocarbons.
State: Colorless, odorless, non-toxic, and non-corrosive liquid.
Temperature: Cooled to approximately -162°C (-260°F) to remain in liquid form.
Specifications
Density: About 0.45 to 0.5 kg/l when liquefied.
Energy Content: High energy density, approximately 55 MJ/kg.
Vaporization: Upon regasification, LNG returns to its gaseous state, expanding significantly in volume.
Applications
Energy Source: Used for electricity generation, heating, and as a fuel for vehicles.
Industrial Use: Employed in various industrial processes and as a feedstock for chemical production.
Export and Import: Facilitates international trade of natural gas, transported in specialized LNG carriers.
Safety and Handling
Storage: Requires cryogenic tanks designed to handle low temperatures and prevent evaporation.
Transport: Transported in double-hulled tankers to minimize environmental risks.
Environmental Considerations
Emissions: Burns cleaner than coal and oil, producing fewer greenhouse gases and pollutants.
Regulations: Subject to strict safety and environmental regulations during production, transport, and use.
