摘　　要：在液化天然气(LNG)接收站实际生产过程中,LNG产生大量的蒸发气体(BOG),在已投产的LNG接收站中,利用BOG预冷管道,对减少经济损失以及环境污染具有重要意义。通过深入分析大口径LNG管道预冷的设施条件和难点风险,因地制宜制定了罐内BOG反向预冷码头卸料总管的工艺方案,并在生产准备中切实落实预防保障措施,在预冷过程中严格实时监控,及时动态调节,确保预冷的安全、平稳可控,实现卸料总管预冷零排放作业,节能增效成效良好。In the actual production process of liquefied natural gas(LNG)terminal,LNG generates a large amount of evaporated gas(BOG).This article deeply analyzes the facility conditions and difficult risks of pre cooling large diameter LNG pipelines,and formulates a process plan for the reverse pre cooling of BOG in the tank terminal discharge main pipe according to local conditions.During the precooling process,strict real-time monitoring and timely dynamic adjustment are carried out to ensure the safety,stability,and controllability of precooling,achieving zero discharge operation of the unloading main pipe precooling,and achieving good energy-saving and efficiency improvement results.
