Thermodynamic Properties of Fluids

CANARY uses the Peng-Robinson equation of state to calculate the thermodynamic properties of fluids. Given the storage conditions (temperature and pressure) and fluid composition (up to 10 components), CANARY calculates the compositions of the gas, aerosol, and/or liquid phases of the released fluid.

Quest uses the properties of fluids following a release as input to a number of vapor dispersion and fire models (also integrated into the CANARY software) which define hazard zones (i.e., toxic downwind travel distances, downwind distance to LFL, distance to thermal radiation levels from a fire, etc.).

Sample calculations may be performed to predict fluid compositions and properties following an adiabatic flash by using our interactive thermo web pages:
