LNG is predominantly Liquefied Methane. Natural Gas turns into Liquefied Natural Gas at -161°C. It is odorless, colorless, non-toxic and non-corrosive. The major advantage is LNG takes up about 1/600th the volume of Natural Gas. This makes LNG cost efficient to transport over long distances where pipelines do not exist. The density of LNG falls between 430 kg/m3 and 470 kg/m3. LNG is less than half the density of water; therefore, as a liquid, LNG will float if spilled on water. The liquefaction process involves removal of certain components, such as dust, co2, acidic gases, helium, water, and heavy hydrocarbons, which could cause difficulty in downstream.
