Dynamic Simulation

Dynamic Simulation studies the real transient behavior of plant equipment as process conditions evolve over time. Dynamic Simulation models the behavior of individual pieces of equipment, interactions between units or an entire plant.

Dynamic Simulation differs from its steady state counterpart by focusing on transient variations of pressure, temperature and flows as processes are subjected to hypothetical disturbances such equipment failure. Such interruptions can lead to overpressuring of relief valves, compressor turn down to recycle operation, liquid accumulation in knockouts and more.

Since actual dynamics are important, physical sizes of process equipment are also included in Dynamic Simulation.

The Benefits of Using Dynamic Simulation:

  • Provides an additional component in overall risk control strategy
  • Increases understanding of the complex interacting behavior of real processes, over time
  • Safeguards against hazards
  • Optimizes operating procedures
  • Expands troubleshooting capabilities
  • Solves problems without test data

KBR Uses Dynamic Simulation Analysis for:

  • Process design
    • Control, recycle, and relief valve sizing
    • Optimum pipe diameters
  • Process control
  • Runaway reactions
  • Anti-surge controls
  • De-bottlenecking
  • Start-ups/shut-down procedures
  • Pipeline packing
  • Process and operator training

Application Examples of Dynamic Simulation:

  • LNG facilities
  • Offshore facilities
  • Petrochemical facilities
  • Refining facilities
  • Common utility systems
  • Plant wide process response
