CANARY is a Consequence Modeling software package that allows the user to model the potential impacts following a hazardous fluid release. CANARY is unique in that it provides thermodynamic calculations for mixtures of up to 10 components.
CANARY integrates multicomponent thermodynamics into the time-varying fluid release simulation. These simulations account for two phase flow, flash vaporization, and aerosol formation, as well as liquid rainout. Vaporization from liquid pools takes into account pool spreading, heat transfer effects, and impoundment. The information generated by these models forms the source term(s) for the hazard models.
CANARY includes a database of over 250 components. The component database and thermodynamics model allow CANARY to handle many types of mixtures and materials, including:
- Light hydrocarbons
- Heavy hydrocarbons
- Liquefied gases
A full list of materials is provided in PDF form here.
CANARY includes application-specific hazard models for vapor dispersion, fire radiation, and vapor cloud explosions. CANARY allows the user to define the hazard endpoints (e.g. gas concentration, radiant flux, overpressure) to determine the extent of toxic gas clouds, flammable gas clouds, fire radiation, or explosion overpressure.
CANARY has a wide range of applications; the software package is flexible and intuitive such that it can be applied to almost any consequence analysis. The flexibility allows users to model releases from pressure vessels, atmospheric tanks, well bores, pipelines, and more. The design and interface allows users to enter and run a case in a matter of minutes. A few projects where CANARY is an invaluable tool are:
- Planning for emergencies
- Performing Quantitative Risk Analysis
- Facility Siting and Layout Studies
- API RP 752 for PSM facilities
- API RP 753 for temporary building siting
- Locating and sizing facility vents and flares
- Code Required Consequence Analysis Studies
- Preparing Safety Cases
- Transportation Risk Analyses
