随着世界石油资源的日益紧张,天然气作为一种清洁、高效的能源,越来越受到世界各国的青睐,天然气贸易正在成为全球能源市场的新热点。天然气从气田开采出来后,通常经过净化处理,在低温常压下液化形成液化天然气,进行储存和运输的。液化天然气英文缩写LNG,其常用的运输形式有两种,一种是船运,一种是管道运输。由于液化天然气常压下的温度为-162°,在运输过程中,要对运输管道进行规模化的冷保温处理。
As the world’s oil resources become more and more tense, as a clean and efficient energy source, natural gas is increasingly favored by all over the world. Natural gas trade is becoming a new hot spot in the global energy market. After natural gas is mined from gas fields, it is usually purified and liquefied at low temperature and pressure to form liquefied natural gas for storage and transportation. LNG abbreviation LNG, its common form of transport in two, one is shipping, one is the pipeline transport. Since the temperature of liquefied natural gas at atmospheric pressure is -162 °, it is necessary to carry out the large-scale cold insulation treatment on the transportation pipeline during the transportation.
