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 1/600th the volume of natural gas in the gaseous state.
- It is odourless, colourless, non-toxic and non-corrosive.
As a Liquid, LNG is not explosive, LNG vapour will only explode if, in an enclosed space, LNG vapour is only explosive if within flammable range of 5%-15% when mixed with air When cold LNG comes in a cloud with warmer air.
It becomes a visible vapour cloud, As it continues to get warmer, THE vapor cloud becomes lighter than air and rises, When LNG vapour mixes with air.
It is only flammable if within 5-15% natural gas in air, less than it is not enough to burn, More than this, there is no gas in the air and not enough oxygen for it to burn.
