Liqueflied natural gas

详情

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).
