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.
