Abstract: Atmospheric storage tanks for flammable liquids are core equipment for storing hazardous chemicals in the chemical industry. Failure of tank integrity can easily lead to major safety accidents such as fires, explosions and medium leakage, which directly threaten the production safety of enterprises and the ecological environment. Aiming at the industry pain points in current tank integrity management, including unsystematic risk identification, disconnected control measures, low informatization level and imperfect management mechanisms, this paper constructs a comprehensive risk identification system from five dimensions—equipment body, safety accessories, process operation, environmental factors and management system—based on the full life cycle operation law of storage tanks. A combination of risk matrix method and Failure Mode and Effects Analysis (FMEA) is adopted to realize quantitative risk assessment and priority ranking. On this basis, systematic improvement paths are proposed from three levels: technical prevention and control, management optimization and informatization empowerment, forming a full-process, closed-loop tank integrity management model. The research results can provide scientific theoretical support and practical references for chemical enterprises to improve the integrity management level of atmospheric storage tanks of flammable liquids and prevent and resolve major safety risks.
