近年来,我国针对东南沿海五省市经济高速发展与能源供应短缺,环境污染日益严重这一矛盾,开始积极研究在上述地区引进 L N G,以增加清洁能源供应,改善过分依赖煤炭的能源结构.首先对世界上 L N G 站的建设与发展作一综述,然后较详细地介绍了我国三个拟建 L N G 站的规模及 L N G 在发电、民用和工业燃料方面的利用情况.由于 L N G 站规模庞大、技术水平高,因此在技术上介绍了 B O G 再冷凝工艺及四种不同类型的 L N G 储罐、三种型式的 L N G 汽化器、 L N G 泵和 L N G 卸料臂等部分关键设备的结构类型和使用材料,并对 L N G 站的经济性进行了简单评估.“,”In recent years,in view of the contradiction among the high speed development of the economy,the short energy supply and the increasingly grave environmental pollution in the four provinces and Shanghai along the coast in Southwest China,a study of introducing LNG for above mentioned regions has been actively made so as to increase the supply of clean energy resources and to improve the energy structure of excessive dependence on coal.In this paper,the construction and development of the LNG stations in the world are first summarized and then the scale of the three planning LNG stations and the utilization situation of LNG for civil and industrial fuels are presented in detail.Because the scale of the LNG stations is large and their technical level is high,so the re freezing technology of BOG and the structural types and materials of a part of key equipments,such as LNG storage tanks of four types,LNG carburators of three types,LNG pumps and LNG unloading arms,etc.,are introduced technically and the economy of LNG station is briefly evaluated.
