Flaresim is the industry standard flare simulation/design application. Designed by professional engineers, for professional engineers, it models thermal radiation and noise footprints generated by flare systems for offshore platforms, gas plants, refineries and chemical plants, and predicts the temperature of exposed surfaces within range.

The application can analyze installations of any complexity, with unlimited multiple flare tips on multiple vertical, horizontal or inclined flare stacks. Users can model pipe flares, sonic flares and liquid burners using a range of algorithms. They can also enter and report data in units of their choice, and can convert data to other units at any time.


Flaresim Features



Flaresim provides full 3D flame-shape analysis with complete flexibility in the location and orientation of multiple stacks, and rapid evaluation of flare systems under different wind speeds and directions. Shield options can be included. 

Working from the opposite perspective, Flaresim allows you to design stack or boom length to meet specific radiation, noise or surface-temperature limits at defined receptor points.



Flaresim includes gas dispersion models for both jet dispersion of flammable gases close to the stack and Gaussian dispersion of pollutants at longer distances. 

The output from Flaresim is highly customizable, and you can select either summary or detailed output. Flaresim has a user-friendly interface and incorporates context-sensitive help at every stage for user guidance.





Training Courses


We are able to provide a range of flare system training courses from narrowly focused introductions to the use of Flaresim to broader based courses that consider the modelling of the full flare system including load generation calculations and flare header design.

Courses can be arranged in-house and we also run public access courses for introducing engineers to Flaresim.

Please contact us for details.

Technical Details

Flaresim comes with full documentation, including a complete description of the program methods and a number of tutorials containing worked examples.

For more information on licensing and software requirements, click read more.

Flaresim is validated to run under Windows 7, 8 and 10. It should also run on earlier versions such as Vista and XP but is not tested for this. Under 64-bit versions of Windows it runs as a 32-bit application. A PC on which you wish to run Flaresim should have at least 1Gb of RAM, and should also have a USB port for connection of the Flaresim security key.

Flaresim is also available in a network version where usage of the software is controlled centrally through a licence server using the Safenet Sentinel RMS system. Licensing is based on the number of simultaneous users of the program. ‘Commuter licensing’ – where licences can be checked out to PCs away from the network – is also supported.
