摘　　要：液化天然气(LNG)储存运输过程中产生的闪蒸气(boil off gas,BOG)具有一定的安全隐患。本文基于前人关于BOG的研究,查阅大量文献,对BOG的主要组成、产生原因和环境影响进行归纳整理,对以往的传统处理工艺以及新型处理工艺进行总结分析,对减少BOG排放量的相关措施进行评述,并总结目前已经得到应用的新技术,以期为今后更高效地利用BOG提供参考。Boil off gass(BOG)is produced during the storage and transportation of liquified natural gas(LNG),and it has potential safety hazard.Based on the previous research of BOG,we looked up and summarized a lot of literatures.The main composition,causes and harm of BOG wered described.The traditional and new treatment process were analyzed.The methods of reducing BOG emissions were reviewed.The new technologies had been applied were also summarized to provide a foundation for more efficient use of BOG in the future.
