(55ag) Simulation of Transient Dispersion Model with Emergency Shutdown Response Time: A Comprehensive Approach

Unignited loss of containment is a significant hazard in the oil and gas industries, posing substantial risks to personnel, property, and the environment. This case study employs computational modeling to simulate and analyze the transient propagation of dispersion based on wind conditions, providing time-varying results for assessing potential hazards to nearby equipment and personnel. The importance of containment strategies in reducing the risks associated with jet fires cannot be overstated. These strategies encompass robust plant design, effective leak detection systems, and reliable pressure relief systems. Therefore, active damage control techniques, such as rapid emergency shutdown (ESD), play a crucial role in influencing process safety. Evaluating the time it takes for the ESD system to activate and bring the process to a safe state is essential. As a result, transient dispersion simulations are coupled with ESD response time assessments to gauge the effectiveness of existing safety measures and suggest potential improvements. This shared knowledge aims to enhance understanding of dispersion and empower industry operators and safety professionals to make informed decisions regarding facility design, optimization of safety systems, and emergency response planning.
