Liquefied natural gas, or LNG, is natural gas in its liquid form. When natural gas is cooled to -161˚C, it becomes a colourless and odourless liquid. This cooling process known as liquefaction, where impurities such as other heavier hydrocarbons, water, carbon dioxide, nitrogen, oxygen and some sulphur compounds within the Natural Gas are removed prior to cooling with the remaining natural gas primarily consisting of methane with only small amounts of other hydrocarbons and nitrogen. The Natural gas is then cooled down to -161˚C and turns into LNG.
Natural gas is the cleanest fossil fuel when burnt, it produces less emissions and pollutants than either coal or oil based hydrocarbons. LNG is more economical to transport across large distances as it occupies only a fraction (1/600) of the volume of natural gas, and therefore takes up less space.
LNG is not explosive, LNG vapour will only explode contained and pressurised within an enclosed space. LNG vapour is only explosive if within the flammable range of 5%-15% when mixed with air.
