There are three primary processes involved in LNG:
Natural gas is transported via pipeline from natural gas fields to a liquefaction plant which is usually located near a port. The gas is cooled to -162 degrees Celsius at which point it becomes a liquid and is stored in specially designed insulated tanks to keep it cold until it is ready to be shipped.
Transportation and Storage
From the LNG plant, liquefied natural gas is pumped through a pipeline system into double-hulled LNG carriers. These carriers are designed to act like a thermos, keeping the LNG cold and minimizing LNG evaporation during its voyage.
When an LNG carrier reaches its destination, the LNG is pumped into insulated onshore tanks. When needed, LNG is warmed to convert it into a gaseous state and delivered by pipeline to residential, commercial and industrial customers.
