LNG and Its Thermodynamics

LNG is the abbreviation for liquefied natural gas, which in this form belongs to the cryogenic liquefied gases. At the source, i.e. in the gas or oil field, liquefaction from the gas phase takes place with a great deal of energy. From there, it is transported by ship at approx. −161 °C (boiling temperature at atmospheric pressure) to customers in Europe, Japan, China, etc. There, the LNG is temporarily stored in large tank facilities at atmospheric pressure or directly regasified for transport in the gas pipelines.
