道化学火灾、爆炸危险指数法在1,3丁二烯聚合安全性评价中的应用

道化学火灾、爆炸危险指数法是在化工领域中广泛应用的一种评价方法,根据该法制定的指数选取规则,可对工艺单元火灾爆炸危险性进行量化和分级.以某化工厂3000t/a三聚体生产项目为背景,从工艺过程、危险物质、安全设施设计等方面,对1,3丁二烯聚合过程火灾、爆炸危险性进行分析；定量评价工艺装置及所含物料潜在危险性,得出主装置区、储罐区固有危险等级,分析不同状态下安全补偿系数对降低危险等级的影响,提出相应安全对策措施.

Application of dow chemical fires and explosive index analysis method in safety evaluation of 1,3 butadiene polymerization process

Dow chemical fires and explosive index analysis method is a widely used evaluation method in the field of chemical industry.According to the index selection rules,the fire explosion risk of the technics cell could be quantitated and classified.In this paper,taking the project of 3000t/a trimer production in a chemical factory as the background,the fire explosion hazard in the polymerization process of 1,3 butadiene was analyzed on the process,dangerous substances,safety facilities design and other aspects.According to the quantitative evaluation of the potentially danger for process units and materials,the intrinsic danger levels of main plant area and tank farm were obtained and some safety countermeasures were put forward by analyzing the effect of security compensation factor on danger level in different condition.
