LNG储罐泄漏的分析和研究

Leakage Analysis of LNG Tank

在液化天然气(LNG)存储过程中,如何防止LNG泄漏已经成为人们关注的重要课题。本文以LNG储罐模型为例,分析泄漏后NG爆炸浓度范围的扩散半径和泄漏时间之间的关系,建立模型,求出函数,绘出关系图,直观看出爆炸半径和扩散时间之间的对应关系,并对LNG储罐消防设备进行简介,为深入的研究奠定基础。

How to prevent leakage of LNG in liquefied natural gas（LNG） storage has become an important topic of people＇s attention. In this paper, the LNG storage tank model is taken as an example to analyze the relationship between the diffusion radius and the leakage time of the NG explosion concentration range after the leakage. The model is established and the function is drawn. The relationship between the explosion radius and the diffusion time is visually observed. And the LNG storage tank fire control equipment is introduced, which will lay a foundation for further research.
