Integration of Bow tie analysis and ALOHA software for risk and consequences evaluation for phase separator in production of methanol route 1 during chemical process development and design / Nurina Aida Mohd Azami

Accidents in the chemical process industries are always dramatic and fatal. Equipment failure is frequently identified as the fundamental cause of many chemical mishaps, resulting in toxicity, fire, and explosions in the sector. The aim of this study is to conduct a hazard and safety evaluation of the chemical process industry, which can be discovered by employing a suitable risk mitigation plan for avoiding and minimizing the detected hazard and assessed risk through Bow Tie analysis and ALOHA modelling software. The Bow Tie analysis method and ALOHA modelling are employed as existing safety analysis procedures in this study, and they will be combined to improve the current safety assessments and their application. This combination is utilized because existing methodologies have difficulties in predicting the threat zone and inability to foresee the clear effects of the threat zone and is unable to predict visually. However, the ALOHA modelling software may determine the distance between the threat zone and the damage range of the hazard effects. ALOHA is required to assess the possibility of an accident occurring in that place. As a result, this study was conducted in order to improve and combine ALOHA software and BOWTIE analysis in order to generate more precise hazard and risk consequences. Both strategies can conceal their weaknesses, making the mitigation plan much easier to apply. A risk and consequences assessment should then be performed to clarify any potential disasters in the future. Mitigation plan is a succinct list of options for making the sector safer.
