Modeling the consequences of hazardous fluids releases is an integral part of any process hazard management program. For most applications within the oil, gas, and petrochemical industry the potential outcomes of a hazardous fluid release fall into categories:
flammablevapor cloud toxicvapor cloud
- torch (jet) fire
- pool fire
- BLEVE fireball
- vapor cloud explosion
Each of these consequence analysis types can be computed using Quest’s CANARY software package, which was designed by Quest engineers and built around a multi-component thermodynamics package. From a list of over 250 components, process streams can be accurately simulated and used in the consequence calculations.
We begin our consequence analysis by calculating the rate of release of the fluid and its thermodynamic state after depressurization to the atmosphere. If the release begins as
In addition to CANARY, Quest engineers draw on a number of other consequence models for specific purposes. These include the use of public-domain consequence models (e.g., DEGADIS or LNGFIRE for LNG) or Computational Fluid Dynamics models to solve complex problems.
