The Next Course in the online PE PDH Course Series, Liquefied Natural Gas LNG - Thermodynamics and Liquefaction Systems Part 3B
By: Ryan Malone
Published: 04/05/2025
In this professional engineer PDH course section (3B), the focus will be solely on the conceptual evaluation of a nitrogen expansion system. The nitrogen expansion LNG liquefier is not the most efficient liquefaction process, but it is considered the easiest to operate, and it lends itself well to making LNG near its tank saturation temperature, which greatly lessens boil-off management problems. Many of the newer small-scale liquefiers, like those for peak shaving plants, use the nitrogen expansion process.
