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 follows on our previous, Part 1, webinar on the topic. The presentation will briefly review the topics introduced in Part 1 focusing on the analytical methodology for fire depressurisation analysis and then discuss through case studies: the conventional workflows and how these can be improved in terms of efficiency, consistency and reduced uncertainty through the use of dynamic flare analysis and optimization.
