Emergency Shutdown System to Prevent Hazardous Chemical Leaks from Petrochemical Facilities during Earthquakes

Key Points

• This study aims to predict the seismic damage levels of petrochemical facilities and propose a proactive emergency shutdown system to minimize hazardous chemical leaks during earthquakes.
• Predicted seismic damage levels of various petrochemical facilities based on different earthquake magnitudes.
• Developed an emergency shutdown system for preventing hazardous chemical leaks during earthquakes.
• Conducted assessments of the seismic performance of existing structures.
• Identified critical earthquake magnitude thresholds that could lead to significant damage in petrochemical facilities.
• Proposed a system that can effectively minimize the risk of hazardous chemical leaks during identified earthquake scenarios.
• Demonstrated the system's potential to reduce secondary damage from chemical exposure.
