According to European Standard EN 1160:1996 liquefied natural gas – LNG is a colorless liquid in which the dominant component is methane. It may contain small amounts of ethane, propane, nitrogen or other components normally found in natural gas. Polish Standard PN-EN 1160:2008 more specifically defines the amount of methane (> 75%) and nitrogen (<5%).
LNG features:
- in an open space, LNG and its vapors are not explosive, odorless and non-toxic;
- does not mix with water or ground but evaporates into the air;
- during the condensation of methane into LNG, the volume is reduced by about 600 times, which significantly reduces the costs of transportation and storage:
- with 1 m³ of LNG you can get 600 m³ of gas that can be transmitted in the network;
- with 1 ton of LNG, we get 1330 m³ of network gas.
LNG Material Safety Data Sheet
LNG is used wherever it is not possible to build gas pipelines and where there are no local natural gas deposits.
LNG is transported in tanks under a pressure of 2 bar and with a temperature of – 162 ° C. The cistern, construction allows the pressure to rise to approx. 7 bar. Tank capacity can vary from 32 m³ (12 t of LNG) for a container tank, and to up to 54 m³ (20 t of LNG) – for a tanker.
Using LNG as a source of energy will allow you to reduce the cost of generating heat for heating and technological purposes.
