Check Valve Applications for LNG Service
What is LNG
Natural Gas comes right out of the ground during the process of extracting crude oil. LNG basically is natural gas that has been cooled to a liquid state and is comprised of mostly Methane. During the liquefaction process, natural gas is cooled to around -260°F (-162°C) at atmospheric pressure, which causes it to condense into a liquid. This liquefaction process removes impurities and allows for more convenient storage and transportation.
How is LNG made?
Raw natural gas enters the process system where impurities are removed. The cleaned gas is then chilled and distilled to remove some more of the natural gas liquids. This partially refined gas is then liquefied to remove the nitrogen gas. The final liquefied natural gas then goes to a storage area before it is transported to its final use destination.
