The Symmetry process software platform 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 the Symmetry platform, 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 user experience has been improved in the Symmetry platform 2022.3 release and new features have been added to provide deeper insight into day-to-day modeling processes.
A new unit operation has been added to model adsorption processes on a steady-state flowsheet. The adsorption unit operation provides both simplified and isotherm modes of modeling. This will enable users to simulate multiple adsorbent layers and breakthrough times using customizable equilibrium isotherms. Adsorption modeling will further assess the impact of operations and process variables on unit performance and optimization.
Flaresim dynamic modeling has been expanded to include fluid temperature and molecular weight. Along with total mass flow, these can now be modeled as a function of time. Users can also specify flare tip and seal pressure drop curves in tabular format to help customize pressure drop calculations.
Improved customization capabilities for the Emissions Summary will enable users to manipulate calculation parameters. Customizable parameters now include CO2 equivalent values, power factor, motor efficiency, and duty cycle times.
The formation of solids can now be predicted with the ability to track four phases in a Symmetry Dynamics model, using the APRNG2 property package. As an example, this feature can be used to predict the formation of solid CO2 or ice during dynamic simulation.
Symmetry-to-XML export functionality has been improved to better handle large and complex simulation cases, with improvements to connection handling and linked variables. The export captures all relevant information needed to recreate the simulation case, including thermodynamic packages, process flow diagrams, component lists, and pseudocomponent lists. The conversion report also provides additional insight into conversion details. Users will benefit from the openness and flexibility that enables them to switch between simulators without loss of information.
