1. What is Liquefied Natural Gas (LNG)?

Liquefied Natural Gas (LNG) is natural gas that has been cooled to -260°F (-162°C) at normal atmospheric at which point it becomes a liquid. LNG takes up 600 times less space by volume than in its gaseous state. This makes LNG far more practical and efficient to transport and store prior to being warmed back to natural gas (regasification). LNg is odorless, non-toxic, and non-corrosive. Without an ignition source, LNG evaporates quickly and disperses, leaving no residue. There is no environmental cleanup needed for LNG spills on water or land.
LNG is primarily composed of methane (85.6% - 8.5%), and Propane (0.0% - 3.0%).
LNG is mainly imported. It is produced from well heads in number of regions in Asia, Middle East, Norway, Trinidad, Tobago, Egypt, Peru, Qatar and Yemen.
LNG is a pure from of natural gas that is neither toxic nor carcinogenic. It emits much less air emissions than other fossil fuels, such as coal and oil. LNg is a very clean and reliable natiral gas for heating, cooling, and for power. While in liquid form, it can be stored and transported at a much lower cost than in its gaseous state.
LNG in a liquid form can be conveted back into a gaseous state with the use of a vaporizer also known as regasification.
LNG in a liquid form does not burn. LNG vapors are flammable, but mix to occure natural gas must be in a 5-15%concentration with air and an ignition source must be present. If the concentration is lower than 5% it cannot burn due to insufficient fuel. If the concentration is higher than 15% it cannot burn due to insufficient oxygen.
LNG is non-toxic, non-corrosive, and odorless. When exposed to the environment, LNG will evaporate rapidly, leaving no residue on soil or water. If LNG is spilled, nothing would remain as it evaporates and disperses quickly. When LNG is used as fuel as compared to oil. It reduces carbon dioxide emission by 25% and sulfur dioxide to almost zero. There are no soot formation and any other particles.
LNG tankers are designed for safety. They are constructed with an outer vessel of carbon steel and an inner pressure vessel made from aluminium or stainless steel. There are several inches of insulation and a vacuum between the outer jacked and inner pressure vessel. The double-walled construction of an LNG tanker is more durable than a similar tanker truck design for the transportation of other liquid fuels such as diesel. LNG tankers also feature safety equipment such as pressure relief valves, and safety shut off valves.
