Abstract
This study suggests a methodology for interactive plant simulation modeling. The developed model integrates a real-time process dynamic simulation with an accident simulation by using object linking and embedding technology. We developed accident simulation models for a residual desulfurization (RDS) process of a petrochemical plant, such as leakage, diffusion, fire or explosion. By analyzing accident types and near-misses of a petrochemical plant, we found several anomality scenarios that could lead to an accident. An overall scenario covers from an abnormal pressure increase in the main discharge valve to accidental gas release through the crack of a pressure recorder. For each scenario, corresponding accident simulation model was developed. We also developed dynamic process simulation models under such accident cases.
Both the accident simulation and the dynamic process simulation are integrated on real-time basis, which could run on an interactive simulation platform. The simulation system can be used for a combined operator training system (COTS) of petrochemical plants. COTS delivers online simulation results to a field operator (trainee) and induces him or her to take proper actions in case that a pre-defined anomaly occurs. It also provides the trainee with the online information on the accident, which is not available in existing operator training systems. The COTS can improve the effectiveness of an operator training system by interactively linking the trainee actions with the simulation model. It can also improve the trainee's competence for confronting probable accidents through training in various accident scenarios.
