CANARY is Quest’s Consequence Modeling software 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 from a list of more than 250.
Using the multicomponent thermodynamics information, CANARY calculates time-varying fluid release rates from a user-described vessel/piping system. These calculations 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 can handle many types of 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) that determine the extent of toxic or flammable gas clouds, radiation from several types of fires, or overpressure resulting from an explosion.
CANARY has a wide range of applications; the software package is useful for any project that requires the calculations of process hazards. A few examples of such projects are:
- Planning for emergencies
- Performing Quantitative Risk Analysis
- Facility Siting and Layout Studies
- API RP753: control room and building siting
- Locating and sizing facility vents and flares
- Code Required Consequence Analysis Studies
- Preparing Safety Cases
- Transportation Risk Analyses
