摘要 LNG是一种无污染、高效、高质量的能源为我国发展天然气工业及优化能源结构，保护生态环境，提高国民经济起到重要作用。近年来，随着我国经济的迅速发展,资源却日益紧缺，LNG作为清洁能源，较汽油和柴油燃烧后的排放物相比，LNG的排放物更少，并且LNG具有能量密度大、运输便捷、安全性能好、经济效益显著等特点，将LNG作为汽车燃料被广泛应用于交通及运输领域，将使得我国的LNG汽车产业迅速发展起来并取得较为显著的经济及环保效益。 该LNG加气站设计采用LNG橇装汽车加气站是将LNG低温储罐、加气机、低温泵、卸车增压器、管道、控制阀门等设备集中固定安装在一个橇块上，具有高度集成、安装简便、机动灵活、安全可靠、操作方便等特点，主要用于LNG汽车加气项目推广和其他小规模客户开发。LNG橇装汽车加气站的技术和建设在我国仍处于发展阶段。 本文通过对基础数据的分析与计算，完成LNG加气站的选址，加气工艺流程的确定，并对流程内的设备进行选型。实现LNG加气站的合理设计。 关键词：LNG加气站 工艺计算 设备选型 流程确定  ABSTRACT LNG is a clean, efficient and high quality energy, development of gas industry to optimize energy structure, protect the ecological environment, improve the national economy plays an important role. In recent years, with the rapid development of economy, our country resources increasingly scarce, LNG as a clean energy, after the gasoline and diesel combustion emissions, compared to less emissions of LNG, and LNG has a large energy density, convenient transportation, good safety and economic benefit is remarkable, the LNG as vehicle fuel is widely used in traffic and transportation, makes the rapid development of LNG vehicle in China and obtain more significant economic benefits, environmental benefits. The skid-mounted LNG stations design USES LNG vehicle LPG stations is LNG cryogenic storage tank, and angry machine, low temperature pump and unloading supercharger, pipes, control valves and other equipment installed in one lump sum, highly integrated, easy installation, flexible, safe and reliable, easy to operate etc., mainly used for LNG automobile gas project promotion and other small-scale customer development. LNG skid car LPG station technology and the construction in our country is still at the stage of development. This article through the analysis of the basic data and calculation, complete LNG stations location selection, the determination of gas process and the selection of equipment in the process. Realize the reasonable design of LNG stations. Keywords: LNG；stations deter
