Symmetry 2024 now available
Wednesday, 28 February 2024
The Symmetry™ process simulation software helps users model process workflows in a single collaborative environment, while integrating pipelines, pipe networks, facilities models, and flare systems to enable consistent thermodynamics and fluid characterization across the whole system. With Symmetry software, users can switch between steady-state and dynamic modeling, optimize processes in upstream, midstream, downstream, and new energy sectors, and maximize the total value of the asset.
The Symmetry 2024.1 release features added capabilities for hybrid modeling enablement, liquid adsorption, and rotating equipment performance curves, enabling faster and deeper insight into process behavior.
Hybrid block
A new hybrid block unit operation facilitates integration between rigorous physics-based models and high-performance AI/machine learning (ML) surrogate models. This unit operation is built to consume any surrogate model built in the Open Neural Network Exchange format (ONNX). Injection of a selected ONNX model will automatically create the appropriate number of input and output variables in the unit operation, enabling connections between these and any other variables in Symmetry software. New workflows empower users to quickly evaluate the performance of a surrogate model, validate its predictions with comparison to a physics-based counterpart, and use the power of the resulting hybrid model for high-performance optimization and process studies.
Liquid adsorption
The adsorber unit operation in Symmetry software has been expanded to support liquid-based adsorption, when solving in simplified isotherm mode. Isotherms are specified on a concentration basis, as an added option to the partial pressure basis available for gas adsorption. The unit operation is also able to solve liquid adsorption with the OLI systems thermodynamic model.
Flaresim™ flare systems design and analysis software receptor point display
An additional layer of customization has been added to isopleth plot display in Flaresim software, enabling users to choose the color of each receptor point. This color selection will consistently apply to the specific point, in every plot it appears in across receptor grids, further enhancing quick interpretation of results and personalized reporting.
Pump performance curve options
The pump, along with other rotating equipment unit operations, now offer the option to directly input performance curve data in a pressure differential basis, eliminating the need to convert vendor data that is provided in this format. This can result in both reduced effort and increased accuracy, by avoiding density assumptions that could introduce significant errors to calculations.
