Evaluation of the Explosion Hazard of a 1-Butene Tank in a Polymer Complex Based on Consequence Analysis

Background: Nowadays, the reduction of incidents, their effects and their consequences have become one of the priorities of organizations. Despite all the efforts made in various sectors to reduce events, every year, there are many events that threaten industrial societies. In order to mitigate the effects of these incidents, prediction and planning are critical to dealing with them. Therefore, the purpose of this study was to evaluate the risk of explosion of 1-butane reservoir in a polymer complex based on an analysis of the outcome using the PHAST software. Methods: This study was conducted in one of the Kermanshah petrochemical complexes in 2016. Necessary geographic information and other basic information were collected. 16 probable scenarios were selected and consequences modeling was done by PHAST software. Results: The modeling results showed that full rupture scenarios and leakage scenarios from the 150 mm hole are the most dangerous scenarios. Conclusion: The results of modeling showed that the larger the leakage size, the associated consequences would be more dangerous and consequently more losses. Due to the capabilities of studied company and the readiness level of the company, it has the ability to respond to the first scenario to some extent.
