What is LNG?
Liquefied NaturalGas or. LNGis a liquid (cryogenic substance) and one of more recent commercial forms of natural gas. Although we must maintain a very low temperature to keep natural gas in its liquid state, the respective physical state and high energy density enable a long-distance fuel transportation.
To liquefy natural gas it must be cooled under -161.6 degrees Celsius (111.55 Kelvin) below boiling point (a basic component of natural gas).
Depending on the source of the gas which is liquefied, LNG consists of 90-100% methane with admixtures of ethane, propane and other hydrocarbons, nitrogen, etc. In terms of volume, LNG occupies only 1/600 of natural gas volume. Liquid density is between 400 and 420 kg/m³. LNG is an odourless blue, low viscosity, non-toxic, non-corrosive liquid.
Its typical lower calorific value is 13.33 kWh/kg or 48.63 MJ/kg. The flash point is at 540°C.
The advantage of LNG is also that in the transition of the physical state from liquid to gas a large quantity of cold is released which can be trapped in a cooling loop to reduce the costs of cold generation. The quantity of cold depends on the use of LNG and temperature regime of a cooling system, but nevertheless we can calculate approx. 240kWh of cold (in 100% efficiency) that we obtain in gasifying 1t of LNG.
Major exporting countries of LNG are Algeria, Australia, Indonesia, Libya, Qatar, Nigeria, Russia, etc.
What is LNG used for?
LNG is a serious alternative to fuels such as coal, heavy fuel oil, extra-light heating oil, liquefied petroleum gas, etc.
It is primarily intended for large industrial customers, large boiler rooms with constant consumption which are not connected to the natural gas pipeline network but would like to reduce energy costs and their carbon footprint.
It is also used in the transport sector, in particular freight road transport.
