Improving the Depth and Accuracy of HAZOP Analysis for Safer Process Development in Chemical Industries

HAZOP analysis has become a versatile tool for industrial risk assessment and optimization in the past decades. It facilitates systematical design review with wide applications spanning across entire project lifecycle, from initial to operation decommission stages. Traditional qualitative process that largely depends on historical experience brainstorming can lead inaccurate hazard identification severe accident consequences. This study aims at improving depth accuracy of by delivering comprehensive exploration critical factors advanced quantitative approach. The impact were illustrated prerequisite assurance aspects. Prerequisite serve as fundamentals which involve technical details, team management, execution strategy HSE culture, while denote PSI data analytical frameworks. A classical chemical case via semi-quantitative method was exemplified. Countermeasures international leading practices introduced summary chart end. Special attention should be paid effectiveness safety guards coming up recommendations. Motivating future works explored such efficiency optimization, finer targeting different types, broader industry applications. By incorporating integrated approach, influence enterprise will more profound enhanced prevention awareness overall environment.
