The majority of existing LNG plants utilize a variation of the propane pre-cooled, mixed refrigerant liquefaction process. This process utilizes
propane refrigerant to chill the feed gas and a mixed refrigerant to achieve liquefaction and sub-cooling. Most recent variations of the process
produce 4.0 — 5.0 megatons per annum (mtpa) of output per train. Greeneld plants will commonly consist of one to three trains with room
for additional trains depending on long term feed gas supply. Larger-scale variations of the process utilize a third refrigerant loop of nitrogen
to achieve sub-cooling, and have been used to achieve nearly 8.0 mtpa of output per train. This “mega train” conguration is featured in the
process diagram below.
