Detailed safety analysis based on high-fidelity models
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. Effective removal of hydrocarbons is achieved by fully utilising the flare capacity while at the same time minimising Passive Fire Protection (PFP).
PSE provides comprehensive pool and jet fire analysis based on our gFLARE® technology. Analysis involves detailed studies of the flare system capacity limitations and the fire depressurisation and relieving events.
Both pool and jet fire scenarios are covered following the API Guidelines (API 521 6ed). The basic principals of PSE's vessel & system blowdown technology are applied, and are coupled with detailed wall stress calculations to provide high-accuracy solutions. Key features include:
- Rigorous thermodynamics
- Accurate system geometry and material (wall, PFP, cladding, insulation) representation
- Fire modelling parameter (emissivity, absorptivity, temperature) and their variation with time and location
- Detailed heat and mass transfer calculation including boiling of liquid inventory
- Detailed stress calculations

The use of a rigorous model-based safety approach based on our gFLARE technology and coupled process and flare network models can result not only in improved process safety but also an improvement in operations and a considerable reduction in CAPEX.
