These models allow engineers to test various operating conditions, predict process performance, and optimize designs for maximum efficiency and safety. Sensitivity analysis can highlight critical parameters.

  • HAZOP (Hazard and Operability Study): A systematic technique to identify potential hazards and operability problems in a process. A team of experts reviews the P&IDs and process descriptions to identify deviations from intended operation and their potential consequences. HAZOP is crucial for ensuring process safety.

  • What-if Analysis: Evaluating the impact of different scenarios, including equipment failures, process upsets, and external factors (e.g., extreme weather). This helps in designing robust and resilient systems.
