Flaresim Ltd

Flaresim is the leading flare radiation software package for design and analysis of flare systems. Features include thermal radiation, temperature and noise prediction and also gas dispersion analysis.



Our consultancy services include flare system design studies and training for flare system design.

About Us

One of the leading companies worldwide in flare simulation, we develop and maintain Flaresim – the industry-standard flare design software for the oil, gas, LNG and refining industries. We also provide training and consultancy services in flare and process simulation worldwide.


Our expert engineers each have more than 25 years’ experience in process simulation. We offer clients the benefit of this vast experience through our Simulation Training, Process Simulation and Engineering Software Development consultancy services, designed to help engineers get the most from process simulation.


We place a priority on providing rapid and informative technical support for our products. Our support is provided by process engineers with extensive experience of real world use of our software.


Flaresim models thermal radiation and noise footprints generated by flare systems, and also predicts the temperature of surfaces exposed to the flare. The application can analyse complex installations with multiple flare tips on any number of flare stacks. It also allows you to work from the opposite perspective, to design stack or boom lengths to meet specific radiation, noise or surface-temperature limits at defined positions.
