Abstract (en)
[origin: EP2796819A2] A method for the liquefaction of natural gas, comprising: - taking unpurified natural gas from a gas well (101); - pre-treating the gas for removing impurities; - performing a first compression stage (201); - performing a first heat exchange stage (202); - performing a second compression stage (203); - performing a second heat exchange stage (204); - performing a third compression stage (205); - performing a third heat exchange stage (206); - performing an additional regeneration heat exchange stage (207); - performing a first main independent heat exchange cycle (208); - performing a second main heat exchange cycle (209); - passing the gas through a Joule-Thomson valve; - sending the liquefied gas (215) to storage; - injecting the portion of the gas remaining in the gaseous state (210) into the second main heat exchange stage (209) and subsequently re-injecting the remaining gas in the gaseous state into the inlet pipe (122) being mixed with the gas incoming from the treatment plant.
