Recommended :Liquefied Natural Gas (LNG) is one of the cleanest energy among all other energy sources.LNG and Supply Chain discussed briefly entire production, transportation, receiving and distribution path of LNG. There are still many peoples who are safety, environment & security concerns, not agreeing with the LNG production as discussed in "LNG SES Issues...".
Liquefy Natural gas is a process of cooling down the natural gas to form liquid for easy storage and transportation. There are few ways to cool down natural gas. Typically are mechanical refrigeration, JT valve and expansion turbine. More discussion in "Techniques to Achieve Cryogenic Temperature". Nowadays, liquefying LNG processes generally adopting combination of two or three techniques as discussed above. Following is a tabulation of a few well-known LNG processes.
