Improved modelling of mixtures
The Phast and Safeti Multi Component (MC) add-on provides improved consequence and risk results for mixtures compared with the traditional “pseudo-component” (PC) approach.
In the “pseudo-component” approach the composition, thermodynamic behaviour and properties of a mixture are calculated using simple averaging equations, whereas in the multi component approach modelling of mixtures involves more rigorous enhancements to the physical property system.
The Multi Component add-on supports the core steady-state discharge models, dispersion modelling via the unified dispersion model (UDM), and the standalone multi component pool vapourisation modelling.
