What is LNG and what are some of its properties?
• LNG (liquefied natural gas) is natural gas, primarily methane, which has been cooled to its liquid state at -260F (162.2C) • Liquefying natural gas reduces the volume it occupies by more than 600 times, making it a practical size for storage and transportation • LNG (the liquid itself) is not flammable or explosive • LNG vapor (methane) is colorless, odorless and non-toxic. Methane can become an asphyxiant when it displaces the amount of oxygen that humans need for breathing • LNG vapor (methane) typically appears as a visible white cloud since its cold temperature causes humidity in the air to condense • Cold LNG vapor (methane) is flammable when it occurs in a 5%-to-15% concentration air.
