Applications of thermal hazard analyses on process safety assessments
In 2011, a large petrochemical complex in Taiwan incurred several fire and explosion accidents, which had considerable negative impact for the industry on both environmental and safety issues. Reactive substances are widely used in many chemical industrial fields as an initiator, hardeners, or cross-linking agents of radical polymerization process with unsaturated monomer. However, the unpredictable factors during the process having risk to runaway reaction, thermal explosion, fire, and exposure to harmful toxic chemicals release due to the huge heat and gas products by thermal decomposition could not be removed from the process. This study used differential technology of thermal analysis to characterize the inherent hazard behaviors of azo compounds and organic peroxides in the process, to seek the elimination of the source of the harmful effects and achieve the best process safety practices with zero disaster and sound business continuity plan.
