The increased interest and use of decarbonisation technologies highlights the importance of establishing the validity of existing consequence tools traditionally used for hydrocarbon and chemical hazards when applied to these new technologies.
DRIFT is an integral model developed by ESR Technology for predicting the dispersion of gaseous and two-phase releases in the atmosphere. The technical paper presents the results of new validation studies comparing DRIFT predictions with previously published dispersion data for hydrogen, ammonia (FLADIS) and carbon dioxide (CO2PIPETRANS). Key aspects differing from previous DRIFT validation are:
- Hydrogen – application at lower molecular weight and higher pressure
- Ammonia – interaction of ammonia with condensed water and the effects on aerosol composition and cloud behaviour
- Carbon dioxide – inclusion of the thermodynamic effects of dry ice sublimation
