摘要:
液化天然气(LNG)作为一种清洁能源在造福人类的同时带来了一些安全挑战。自20世纪克利夫兰发生了严重的LNG泄漏火灾事故并造成大量的人员伤亡以来,众多学者开始重视液化天然气安全问题,并展开工作分析LNG主要危害,研究LNG危害防护措施。本文介绍了LNG的危险特性并综述了20世纪克利夫兰事故发生后至今主要的LNG泄漏扩散和池火灾分析以及防护研究工作。LNG危害分析工作包含LNG泄漏源项、蒸气扩散以及池火灾等主要危害分析; LNG危害防护工作涉及堤堰防护LNG泄漏,利用水幕和高倍泡沫控制LNG气体和火灾灾害研究等; 并建立了数值模型描述LNG泄漏及相关事故危害特性,为进一步研究LNG灾害和防护提供了理论基础。针对LNG池火灾事故的热辐射危害,其事故预防、危害分析及危害控制仍需深入开展研究。本文展望了今后LNG池火灾危害分析和利用堤堰及高倍泡沫进行危害防护研究的主要方向。
Abstract:
As a clean energy source, liquefied natural gas(LNG)brings safety challenges while benefiting mankind. Since the serious LNG leakage fire accident in Cleveland in the last century caused a large number of casualties, many scholars have begun to pay attention to the safety of LNG, work to analyze the main hazards of LNG and study the protection measures for LNG hazards. With the introduction of the hazard characteristics of LNG, the main LNG leakage spread and pool fire analysis and protection research work since the Cleveland accident were summarized. The LNG hazard analysis includes the study of LNG spills source term, vapor dispersion and pool fires; LNG hazard protection involves the application of dike, water curtain and high expansion foam to control LNG spreading, vapor dispersion and pool fire hazards. The established numerical models can describe the LNG release and following consequences, which provide a theoretical basis for further study on LNG hazards and protection. In view of the thermal radiation hazard of LNG pool fires, additional work is needed to study incident prevention, consequence analysis and hazard control, including fire hazard analysis and the use of dike and high-expansion foam for hazard prevention and control.
