Advanced dispersion modelling

Current dispersion models used in process hazard analysis studies have certain limitations – most notably with regards to modelling time-varying and short duration releases.

Webinar key learning points:

  • What are the current limitations in popular dispersion modelling techniques?
  • How do these affect consequence results and in particular dispersion modelling predictions such as toxic hazard ranges?
  • We will demonstrate the improvements from legacy approaches through case studies using the latest version of Phast process hazard analysis software (version 8).
The primary benefit is more accurate and realistic-looking dispersion results.
