LNG is a price-competitive source of energy that could help meet future economic needs. Since LNG occupies only a fraction (1/600) of the volume of natural gas, and takes up less space, it is more economical to transport across large distances and can be stored in larger quantities. Natural gas can be imported from distant sources in the form of LNG. It produces less emissions and pollutants than either coal or oil. Natural gas is the cleanest burning fossil fuel. To carry out the conversion of road, air, railway and river transport to gas fuel with use of LNG as a vehicle-borne reserve. To create a reserve stock of LNG fuel with its further re-gasification and feed to Consumer To supply gas to objects (boiler-houses, human settlements), that are far away from gas-distributing systems The implementation of efficient cryogenic technologies with use of LNG allows: These efficiency improvements make LNG an increasingly competitive energy source, particularly in the high-demand markets of Asia, Europe and the United States. New technology has led to tankersĪnd other LNG infrastructure being substantially larger and more costefficient than in the past. But advances in technology are transforming LNG into an increasingly global energy option, similar to oil. Historically, natural gas has been viewed primarily as a regional energy supply source because it was transported to markets via pipelines. These countries include Algeria, Australia, Brunei, Indonesia, Libya, Malaysia, Nigeria, Oman, Qatar, and Trinidad and Tobago. LNG takes up much less space than gaseous natural gas, allowing it to be shipped much more efficiently.Ī majority of the world’s LNG supply comes from countries with large natural gas reserves. Liquefied natural gas (LNG) imports represent an increasingly important part of the natural gas supply picture. The increased use of LNG is allowing for the production and marketing of natural gas deposits that were previously economically unrecoverable. This is accomplished using a regasification process involving heat exchangers. When natural gas is needed, the LNG is warmed to a point where it converts back to its gaseous state. The boil-off gas is collected and used as a fuel source in the facility or on the tanker transporting it. The temperature within the tank will remain constant if the pressure is kept constant by allowing the boil off gas to escape from the tank. LNG is characterized as a cryogen, a liquefied gas kept in its liquid state at very low temperatures. If LNG vapors are not released, the pressure and temperature within the tank will continue to rise. These tanks can be found above or below ground and keep the liquid at a low temperature to minimize the amount of evaporation. When LNG is received at most terminals, it is transferred to insulated storage tanks that are built to specifically hold LNG. Because it is easy to transport, LNG can serve to make economical those stranded natural gas deposits for which the construction of pipelines is uneconomical. While LNG is reasonably costly to produce, advances in technology are reducing the costs associated with the liquification and regasification of LNG. While there is no combustion, this physical explosion can be hazardous to any nearby person or buildings. A large amount of energy is released during this rapid transition between phases and a physical explosion can occur. Heat is transferred from the water to the LNG, causing the LNG to instantly convert from its liquid phase to its gaseous phase. When enough LNG is spilled on water at a very fast rate, a Rapid Phase Transition, or RPT, occurs. LNG vapor is only explosive if within the flammable range of 5%-15% when mixed with air. LNG vapor will only explode if in an enclosed space. If it is more than 15 percent natural gas in air, there is too much gas in the air and not enough oxygen for it to burn.Īs a liquid, LNG is not explosive. Five percent natural gas in air, there is not enough natural gas in the air to burn. ![]()
