Cov pa roj ntsha, tom qab kev ua kom huv (tshem tawm ntawm CO2, sulfides, hnyav hydrocarbons, dej, thiab lwm yam impurities), yog cryogenically txias rau -162℃nyob rau hauv ib txwm siab, hloov ntawm lub gaseous xeev mus rau lub xeev kua, hu ua liquefied natural gas (LNG). Qhov ntim ntawm LNG yog kwv yees li 1/620th ntawm tib qhov loj ntawm cov nkev, thiab nws qhov hnyav yog kwv yees li 45% ntawm tib lub ntim dej.
Kev faib tawm: LNG refueling stations yog refueling stations supplying liquefied natural gas (LNG). Lawv feem ntau muab faib ua plaub hom:
1. Skid-mounted refueling chaw nres tsheb
2. Txheem refueling chaw nres tsheb
3. L-CNG refueling stations
4. Mobile skid-mounted refueling stations
