Computer Simulation of an Incident in a Gas Processing Plant Case Study The Challenge An incident at a gas processing plant centered around the loss of liquid level and breakthrough of a high pressure two-phase mixture into low pressure equipment (HP/LP Interface) leading to cold temperatures and subsequent brittle failure of a vessel. The case team needed to confirm or rule out operator actions that could have led to the incident. The individual events and actions that lead to the incident happened over a period of several hours. The process was so complex that careful study by many experts was unable to clearly identify the cause-and- effect of each of the events and actions. Our Approach To study the events that lead to the incident, a dynamic computer simulation was created by ioMosaic
