Symmetry Flare offers flare- and relief-system design tools you can use to verify the performance of the entire safety system, with steady-state or dynamic parameters, and reduce capex.

Unique integrated approach

No more importing process data. In Symmetry Flare, you can model any process with steady-state or dynamic simulation. Integrated models can span your entire operation, from a gathering network through to gas processing and refining facilities. You can simulate the entire scope at once without error-prone data transfer and use the process model to identify relief scenarios, including overpressure events, operational flaring, and blowdown.

Optimum design scenario

Combine steady-state and dynamic analysis in the same simulation as needed for each scenario. Use steady state to quickly calculate required relief, and use dynamics to model peak flows, record and playback profiles, and directly connect to a dynamic flare header.

Rigorously model any scenario in dynamics, including detailed blowdown and depressuring studies, fire with built-in heat input calculations (including radiant heat transfer), equipment or utility system failures, startup, shutdown, and operating procedures.

A variety of sequencing and control tools, including an event scheduler, cause-and-effect matrix, and control scheme modeling, offer complete modeling flexibility and ensure reliability.

Flexible and intuitive solution

Symmetry Flare offers capabilities to ensure safer relief-valve installation across all scenarios. Valves can be modeled alone, with piping, or with the header network. The sizing and selection workflow determines the governing scenario and evaluates capacity of the selected orifice size (API or ASME). The workflow also provides warnings for undersized valves and significantly oversized valves that may chatter. Inlet piping can be modeled to verify that inlet pressure losses will not cause stability issues: a steady-state model will check the 3% rule across all valves and scenarios; then, you can model scenarios with potential issues in dynamics to verify true potential for chatter. Users can verify maximum-allowed backpressure (MABP) along with inlet and tailpipe constraints at design or rated flow.

Safer Design

Verify the safety of your design by evaluating thermal radiation, noise, surface temperature of exposed objects, and flare gas dispersion using data from your network model across scenarios.
