The fully-integrated Flare workspace allows models to suit any application. Users are empowered to analyze standalone components or complete systems, with various levels of detail, in steady-state or dynamics.
An existing process model can define conditions for a relief valve sizing and installation model, which may evolve into a header rating model with constraint evaluation across global scenarios. These flare models are easily updated when there are changes in the process.
A scenario-driven model of the header system can report an increase in backpressure on a relief valve, automatically trigger an update to valve rating calculations, and verify inlet losses at the new rated flow. Likewise, a change in relief valve size or type is automatically taken into account in header constraint evaluation.
The unique level of integration between steady-state and dynamics solvers in the Symmetry platform allows users to analyze the bulk of scenarios in steady-state and invest in dynamics analysis where it matters.
Critical scenarios can be solved in dynamics, starting from the steady-state model and adding details and scheduled events for rigorous time-based analysis. Dynamics gives insight into the severity of constraint violations, including the duration of a violation and the real impact on equipment behavior. Taking into account system volumes and staggered relief times makes for a more realistic analysis, and in many cases will result in conditions being farther from constraint violation or requiring less drastic (and expensive) upgrades to meet safety criteria.
Using the right tool for an application is seamless in the Flare workspace, without transfer of data across applications or a spread of models across separate environments, so users can reap the benefits with less effort.
Define relief scenarios for standalone sources and/or full header networks to verify that the model meets safety constraints for every potential event. Constraint limits for relief valves and the header network are monitored, and key results are shown per scenario, color-coded and sorted for efficient identification of bottlenecks.
Active scenario selection provides users access to any variable calculated in a scenario, including all the hundreds of property profiles and variables available in unit operation forms, as well as built-in access to multiple post-analysis tools that allow for deeper analysis and system understanding.
The Flare workspace builds upon the legacy of VMGSim technology and helps users get the most out of their flare models with the Symmetry platform. Industry-proven thermodynamics from VMGThermo enable accurate prediction of properties, consistent characterization across models, and detection of vulnerabilities like hydrate and solid formation. The steady-state, dynamics, and network solver engines bring decades of experience solving related systems in industry, with the steady-state network solver now adding kinetic energy tracking for flare applications. The Symmetry platform has a variety of tools including case studies, emission monitoring, and a new equipment database that enable deeper, asset-wide insight.
Define relief scenarios for standalone sources and/or full header networks to verify that the model meets safety constraints for every potential event. Constraint limits for relief valves and the header network are monitored, with inlet and tailpipe constraints optionally evaluated at the required or rated flow.
Valid sources are automatically detected from Flare flowsheets and assigned relief conditions as specified in the running scenario. Key results are shown per scenario in the Flare Scenario Manager, color-coded and sorted by their approach to constraint violation for efficient identification of bottlenecks.
Active scenario selection defines the specifications and results shown on the flowsheet. Switching to a previously-run scenario restores its network solution with all calculated values. Users have access to any calculated property in a scenario by opening unit operation forms and delving into the hundreds of property profiles and variables available, as well as having access to multiple post-analysis tools like case studies, the line list, and a flow path viewer.
