Flaresim Software Flaresim is our highly developed and sophisticated 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 analyse 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.
