Symmetry Process Software (commonly known as Symmetry) is a process simulation and design software platform used by chemical, petrochemical, natural gas, refining, and energy industries for steady-state process modelling, engineering analysis, equipment design, and process optimization. The software is developed by SLB and is used for the simulation of fluid properties, chemical processes, separation systems, heat transfer operations, and integrated production facilities.
Symmetry combines rigorous thermodynamic modelling with process simulation capabilities and is designed for applications ranging from conceptual process design and debottlenecking studies to operational troubleshooting and digital engineering workflows.
History
[edit]Symmetry traces its origins to the work of Virtual Materials Group (VMG), a Canadian software company founded in the early 2000s by researchers and developers specializing in thermodynamics and process simulation technology.
VMG was established to develop advanced thermodynamic property packages and process simulation tools for the hydrocarbon processing industry. Early contributors included Marco Satyro, Yau-Kun Li, Craig Morris, Raul Cota, and Glen Hay. One of the company's early commercial projects involved the development of PetronasSim, later renamed ICON, a customized process simulation platform developed in collaboration with PETRONAS.
During this period, Craig Morris developed Sim42, an open architecture process simulator that provided part of the foundation for the software architecture later incorporated into VMG simulation products.
VMG's simulation platform evolved into VMGSim[1], which subsequently became known as Symmetry Process Software following product and corporate development initiatives.
In 2015, VMG was acquired by Schlumberger, which later rebranded as SLB. Following the acquisition, Symmetry became part of SLB's Digital and Software portfolio serving the process industries.
Features
[edit]Symmetry provides capabilities including:
- Steady-state process simulation
- The equation of state formulation used by VMG... is called Advanced Peng-Robinson for Natural Gas (APRNG).
- Thermodynamic property prediction and management
- Natural gas processing simulation
- Refining and petrochemical process modelling Equipment sizing and rating
- Heat exchanger analysis
- Process optimization studies
- Flow assurance and integrated production modelling Digital engineering and operational support workflows
A key prerequisite for the simulation package was the ability to be fully integrated within the existing plant DeltaV™ control system.
Applications
[edit]Symmetry is used across a wide range of industrial sectors including:
Oil and gas production Natural gas processing LNG facilities Refineries Petrochemical complexes Carbon capture and storage projects Hydrogen and energy transition applications Chemical manufacturing
VMGSim has been used in integrated geothermal reservoir and process simulation studies[2]
VMGSim has been used for thermodynamic modelling of integrated fuel processor and polymer electrolyte membrane (PEM) fuel cell systems, including studies examining control strategies for handling variations in LPG fuel composition. [3]
Applications include process design, revamp studies, facility optimization, operator training support, troubleshooting, and digital twin implementations.
Industry Integration
[edit]Symmetry can be used alongside other engineering software platforms within the process industries and is often applied in integrated workflows involving process simulation, production modelling, and facility design studies.
The software has been used by major energy companies, engineering contractors, research institutions, and technology licensors.
Notable Developments
[edit]The platform incorporates specialized technology models developed through collaborations with industry licensors and operating companies. These include process models for hydrocarbon processing applications, thermodynamic property packages, and furnace and reactor modelling technologies used within the refining and petrochemical sectors.
Research published in Energy & Fuels introduced an extended PIONA characterization methodology implemented in VMGSim to enable simultaneous tracking of molecular structure and thermodynamic properties in refinery simulations.[4]
