Latest release of DNV GL Phast makes behavior of toxic clouds easier to predict; along wind diffusion method 27 November 2017 The latest release of Phast , DNV GL’s software for process hazard analysis, brings in an entirely new dispersion model that increases accuracy in predicting the movement of certain types of toxic clouds. The new model significantly improves predictions of releases with short durations—a particular challenge for the modeling of hazardous dispersions. Companies using the software will benefit from decisions that are based on more realistic models, thereby increasing efficiency and safety in the design and operation of assets where accidents could cause hazardous releases. Previous models have assumed the duration of a release is long enough for it to reach a steady state, which may not be the case. The dispersions of short-duration clouds are affecte...
