Our Packages
-
Standards Models
This is the simplest way to get results at the lowest price for simple releases from tanks or vessels. By using Phast defaults for the majority of the parameters, you are able to specify releases for three different weathers and concentrations.
- Tanks or vessels only
- Using Phast defaults
- Commonly stored/used materials only -
Advanced Models
Requiring more detailed information about the release this is a good choice for releases that are not from tanks or pressure vessels. You are still able to specify releases for three different weathers, with optional bunds or dykes and concentrations.
- Simple mixtures
- Piping leaks or ruptures
- Partially flashed liquids -
Sophisticated Modelling
This allows you to specify any release scenario supported by Phast and specify in detail all the parameters required.
- Unusual chemicals or mixtures
- Specific modelling options chosen
- Detailed geometrics
- Building fires
- Toxic effects on people indoors -
Phast Consulting Service

Sample Reports
Below are some examples of the kind of reports we can provide to clients. Some of these reports are standard deliverables while others are used for moderate or complex models, or specific client requirements.
Most of these results are for 650 kg of liquid ammonia, stored at 25 °C, leaking horizontally through a 9 mm hole, 0.15 m off the ground, with no bund or dyke.
