LNG fundamentals explained in the Encyclopedia of refrigeration

The IIR has just released a new summary document on liquefied natural gas (LNG) prepared with Heinz Bauer, member of the A2 commission “Gas liquefaction and separation”.  Available on the IIR’s new online Encyclopedia of refrigeration, the document provides an overview of LNG production processes. LNG is a topic of interest for the IIR because the liquefaction of natural gas is achieved through several refrigeration cycles and accounts for about 30 to 35% of the total energy required for the LNG value chain. 

This summary document also addresses the technologies for using the cold energy recovered during the regasification stage, namely highlighting their potential in terms of energy efficiency. Indeed, the regasification of LNG releases a significant amount of cold energy that can be reused in various processes, such as electricity production or carbon capture.
