摘要
液化天然气作为一门新兴的工业，近３０年来持续高速发展，展示了其强大的生命力。ＬＮＧ作为不可替代的能源，在运输、储存、开发、利用等方面独具特点。包括预处理、液化和储运三个主要部分的天然气液化技术，在国内已经取得实质性的进展，技术成熟，能够实现工业化生产，从而奠定了液化天然气工业的基础。威远天然气化工厂近期开发的采用带透平膨胀机致冷的克劳得循环代替焦尔—汤姆逊节流效应的制冷循环，具有设备少、工艺流程合理、冷量自给勿需外加冷剂及能量消耗低的特点，提高了天然气液化技术水平。目前，国内发展ＬＮＧ工业的呼声很高，尤其是它作为汽车燃料引起了广泛的关注，现正建的ＬＮＧ装置有２套，开展前期工作的ＬＮＧ工程项目有３项。这些工程的建设标志着我国ＬＮＧ工业的飞跃发展，预示了它美好的发展前景。
As a non-replaceable energy, Liquified Natural Gas (LNG) have many special characteristics on transportation, storing, developing and utilization. Technology of natural gas liquifing, concluding pretreating,liquifing and storing, has so essentially developed that can produce industrialized at home. Replacing Joule-Thomson throttle effect by Claude cycling with turbine expansion engine to freeze, developed by Weiyuan Natural Gas Chemical Plant recently, have some features such as a few equipments, process reasonable, freeze capacity self-sufficient and low energy consuming.
