PSE has a track record in safety projects since 2012. The Process Safety Practice has completed over 200 safety consultancy projects, using the company’s inhouse high-fidelity safety technology, which has become the gold standard for a number of operators.

The release of gPROMS Flare (gFLARE) now makes PSE's leading safety technology available to engineers worldwide.

gFLARE provides a set of capabilities for simultaneously enhancing safety while reducing CAPEX and OPEX. It allows engineers to safely design out the use of low temperature materials and fire stress risk, as well as optimize the flare height, headers and equipment size.

gFLARE also provides significant advantages in combining depressuring, relief and flare design in one environment. It allows early integration to avoid impact on the project schedules.

gFLARE at-a-glance

gFLARE satisfies the growing market demand for consolidated tools modelling both relief and flare dynamics:

Overpressure protection – the old vs the new

The following brief comparison illustrates the difference between the traditional and gFLARE approaches for overpressure protection:

The conventional approach

The conventional approach uses low-fidelity lumped models

  • Gas/liquid phases are assumed to be in equilibrium
  • Models are unable to accurately track phase temperatures
  • They are unable to reproduce experimental data
Typical results are shown in the plots below:

State-of-the-art gFLARE

gFLARE’s distributed approach makes no assumptions of equilibrium. Because of the distributed systems approach, accurate phase temperature tracking is possible, and the models can reproduce experimental data accurately.

The difference can be seen in the plot below:


gPROMS Flare can be supplied to consultants and EPCs as a stand-alone package, or the Process Safety libraries can be added as optional extras to a gPROMS Process licence.
