Process Vessels Under Fire: Wall Dynamics & Consequence Analysis


Vessel wall dynamics analysis is a valuable tool capable of predicting not only when the vessel is expected to fail (i.e., stress due to internal pressure is greater than the ultimate tensile strength) but also at what temperature, pressure, and fluid composition. These conditions form the basis for consequence analysis. The available internal energy in the system is a source of fragmentation and deformation energy for the vessel shell, kinetic energy imparted to contents and fragments, and blast wave energy.

This technical training program will review and address the following:

  • Vessel under Fire: wall dynamics heat transfer theoretical concepts
  • Analysis due to over-temperature and overpressure
  • Dynamic Simulation of a given case study using SuperChems™
  • Analysis of the results from dynamic simulations. Criteria for implementing risk reduction measures
    • Ensuring the Emergency Relief System with the aim to avoid vessel failure due to overpressure
    • Avoiding or increasing the Time To Failure (TTF) of a vessel under fire exposure due to over-temperature; i.e., minimizing domino effect / escalation
    • Sensitivity analysis by considering several risk reduction measures; e.g., fire-proof insulation, sprinklers
    • Consequence modeling from conditions predicted at the TTF using SuperChems™

Who Should Attend

This training is ideally suited for process engineers interested in learning how to evaluate the behavior of process equipment under fire exposure. The vessel wall segmentation approach illustrated during the training course is valuable for sensitivity analysis when considering the some of the following key four (4) parameters that could be installed in the system and which directly influence the TTF prediction:

  • Optimization of the emergency relief system size
  • Definition of the activation time and size for an emergency depressuring valve
  • Minimum insulation thickness and material properties to be considered (i.e., thermal conductivity, heat capacity)
  • Minimum required cooling load and duration if sprinkler systems are considered to be installed
