LPG罐区危险性的研究及分析

Research and Analysis on the Hazard of LPG Tank Area

目前,绝大多数危险性评价所研究的对象是单一的危险源或危险过程。但是,在日常工业生产中,常常会出现由于初次事故能量的释放而导致的二次甚至多次事故的发生。随着工业生产的大型化,储存量的递增使得多米诺事故发生的可能性也在增加。LPG储罐区正是发生此类事故的危险区域。通过相关模型的运用评价了在LPG储罐区发生火灾爆炸后,相邻危险源发生多米诺事故的可能性,并对安全间距作了着重的分析。

At present, the research objects of most hazard assessment are single hazard resource and process. But in daily industrial production, secondary and even several times of accidents Can be happened, resulted from the release of energy of the initial accident. With the change of large - size of industrial production and the increase of storage amount, the possibility of the happening of the domino accidents is also increasing. LPG tank area is just this kind area in which the accidents can be easily happened. The possibility of domino accidents happening because of the related hazard sources is evaluated by using the related models when fire happens in LPG tank area and especially analysis is conducted on safety distance.
