LNG是天然气的液态形式,具有无色、无味、不易燃,无毒,易于储存或运输的优良性质。LNG占天然气体积的1/600。在大气压下约-162℃,-259℃时,变成液态。自从1917年世界第一个液化天然气工厂在美国西佛吉尼亚建成之后,LNG作为天然气的一种储存运输模式,以其独特的优势在近年来迅猛发展。世界生产的天然气中有26.5%被用来做贸易交易,而液化天然气LNG只占贸易交易中的27.8%。
LNG is a liquid form of natural gas, with excellent properties of being colorless, odorless, nonflammable, non-toxic, easy to store or transport. LNG accounts for 1/600 of the volume of natural gas. At atmospheric pressure about -162 ℃, -259 ℃, become liquid. Since the world’s first liquefied natural gas factory was built in West Virginia in 1917 in 1917, LNG, as a natural gas storage and transportation mode, has enjoyed rapid growth in recent years due to its unique advantages. Of the world’s natural gas production, 26.5% are used for trade transactions, while liquefied natural gas (LNG) accounts for only 27.8% of the trading volume.
