Aiming at the potential safety hazards in large-scale coal chemical storage and transportation facilities,this paper systematically analyzes the inherent risks such as flammability,explosibility,process complexity,and accident chain reactions.It points out the inadequacies of current safety control technologies in terms of valve reliability,interlock control,and leak detection.On this basis,a series of innovative technical optimization countermeasures are proposed from the perspectives of material optimization,algorithm improvement,and multi-sensor fusion.The effectiveness and feasibility of related technologies are verified through the application practice in the methanol tank area of a coal chemical industrial park.The results show that the failure rate of fire valves decreased by 95％,the interlock failure rate of loading arms decreased by 91％,and the leak accident rate decreased by 97％,effectively improving the intrinsic safety level of the facility.
