Description

Liquefied natural gas (LNG) is natural gas  (predominantly methane CH4) that has been converted to liquid form for ease of storage or transport. It takes up about 1/**0th the volume of natural gas in the gaseous state. It is orderless, colourless , non toxit  and non corrosive  Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefication process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocaborn , which could cause difficulty downstream. The natural gas is then condense into a liquid at close to atmospheric pressure by cooling it to approximately −**2 °C (−**0 °F); maximum transport pressure is set at around *5 kPa (4 psi).
