摘　　要：[目的]LNG(液化天然气,Liquefied Natural Gas)储备中心气化区工艺设备运用的技术分析与调研,是为解决西安引镇LNG应急中心气化区单一空温气化器编组运行结霜结冰问题而展开。[方法]内地在用的LNG气化技术主要有空温式与水浴式气化两种形式,空温式气化器在大负荷与低温季节运行时,设备周边易起浓雾,外表常会结霜结冰,水浴式气化器则无此现象。通过调研比较近年各地LNG储备中心以及沿海LNG接收站等各类场站气化工艺区气化设备的运行情况,工程上采用独立的LNG水浴式气化器能够实现设备外表无霜冰雾的气化生产;利用水浴式气化器与空温式气化器组合系统联合优化LNG的气化运行,既可获取利用空气蕴含的热能进行LNG气化生产,也能消除低温起雾及冰霜对LNG气化生产的影响。[结果]内地大储存量液化天然气的气化工艺,能够不受低温影响,顺畅完成气化过程的生产。[结论]构建绿色能源体系,基于新型能源网络的形成,高效能源输配与储存转换技术以及天然气与风光水氢等气电再生清洁能源的融合互补发展,完善的储能工程与技术具有重要支撑作用,大型LNG气化技术的优化是一项重要的工程实践。[Introduction]The technical analysis and investigation on the application of process equipment in the gasification area of the LNG(Liquefied Natural Gas)emergency reserve center,is carried out to solve the problems of frosting and icing in the operation of a single grouping of ambient air vaporizers,in the gasification area of Xi'an Yinzhen LNG emergency reserve center.[Method]The LNG gasification technology in use mainly included ambient air vaporizing and water-bath vaporizing in Chinese Mainland.When the ambient air vaporizer was operated with high load and in low temperature seasons,it was easy to fog around the equipment,and the equipment surface would always be covered with frost and ice but the water-bath vaporizer did not have this phenomenon.After the investigation and comparison of the operation of gasification equipment in various station gasification process areas,such as LNG reserve centers and coastal terminals in recent years,the independent LNG water bath vaporizer could realize the gasification production without frost,ice and fog on the surface of the equipment in engineering;The combined operation system of the water-bath vaporizer and the ambient air vaporizer could combine and optimize the LNG gasification,which could not only obtain the heat energy contained in the air for LNG gasification production,but also eliminate the impact of low-temperature fogging,ice and frost on LNG gasification production.[Result]The gasification process in Chinese Mainland of LNG with large reserve can smoothly complete the production without being affected by low temperatures.[Conclusion]To build a green energy system,based on the formation of a new energy network,high-efficiency energy transmission,distribution,storage and conversion technologies as well as the integration and complementary development of the natural gas,wind,solar,water,hydrogen,and other renewable clean energies for gas power generation,have important supporting roles in perfecting energy storage engineering and technology,thus the optimizat
