The aim of depressuring in a fire emergency situation is to prevent possible catastrophic escalation. This is achieved by routing hydrocarbons into the flare network. The effect is not only to remove the flammable inventory from the system but also to reduce stresses in pipes and vessels.

This webinar will discuss changes in the 6th edition of API 521 on fire analysis. The presentation will introduce the analytical methodology for fire analysis; then examine the impact through case studies.

Topics covered

In this webinar you will learn about:

  • A brief introduction to fire analysis
    • Why is it performed?
    • What types of fire are considered?
    • What decisions are informed by the analysis?
  • Changes in the 6th edition of API 521 on fire analysis
  • Description of the analytical method and its validation
  • Fire analysis workflows
    • Targets: flare capacity limit, rupture
    • Conventional workflows for fire analysis
    • Workflow improvements
  • Case studies
    • Slug catcher staged blowdown sizing
    • Reducing Passive Fire Protection requirements on an onshore facility using dynamic flare network simulation
