A Closer Look at the Life Cycle of LNG Dec 12, 2013

The value chain for liquefied natural gas, or LNG, begins when natural gas is extracted from reservoirs located underground. From that point, it is then transferred through a pipeline to the selected liquefaction facility. At the facility, impurities will be removed from the gas. Once oxygen removal and carbon dioxide removal has taken place, the gas will then be sent through three different cooling processes. The end goal is to ensure that the gas reaches a temperature of -260 degrees Fahrenheit. 

After the gas has been sufficiently cooled, it is then termed Liquefied Natural Gas and can be transferred to special tanker ships. While aboard the tankers, the LNG will be kept chilled throughout the duration of the voyage until it reaches its final destination port. At the final port, the LNG can be offloaded into massive storage tanks before being converted back into a gaseous state. Once returned to its original state, the LNG will be transferred into pipelines for the purposes of delivery to power plants, consumers and industrial customers.
