Consistent and customizable receptor point display

An additional layer of customization has been added to isopleth plot display options, enabling users to choose the color of each receptor point in their model. This color selection is consistently applied to the point in every plot it appears in across receptor grids, further enhancing quick interpretation of results and the ability to generate personalized reports.

Account for changes in fluid properties over time

Flaresim software dynamic modeling has been expanded to enable input of fluid temperature, molecular weight, and lower heating value (LHV) over time. This information is critical for accurate determination of the peak relief rate and its duration.

Extended options for flare tip sizing 

Tip sizing calculations support new pressure-based design parameters like inlet pressure and pressure drop at both the seal and tip. Previously available design parameters, such as “Mach number” and “Tip ID” offer improved accuracy, as they now also take the impact of pressure drop into account.

Tip and seal vendor data input

Flaresim software now offers the option to take vendor data into account when calculating pressure drop across the flare tip and/or seal by enabling user input of this tabular data. Curve data may also be saved after input and then easily loaded into other tips or cases.

Integration with Symmetry flare workspace 

Flaresim software flare safety calculations are available within the Symmetry flare workspace. The units displayed in Flaresim software-generated isopleth plots can now be customized from within Symmetry software. Similarly, users can now customize isopleth colors, plot details, and contour details from Symmetry software for increasingly seamless integration.
