Process Simulation
Virtual Materials Group Virtual Materials Group (VMG) is focused on developing high quality and cost-effective software for the process industries. Their flagship products are VMGSim, the new standard in steady state process simulation, and VMGThermo, the standard physical property package system. VMG provides proven, validated and robust thermophysical property prediction packages for the hydrocarbon, chemical and petrochemical industries. Their thermodynamic models are backed by extensive experimental data and support provided by their technical support team. VMGSim The power of VMG's thermodynamic packages is available in VMGSim, an easy to use steady-state process simulator that integrates a state of the art steady state process simulation kernel, Microsoft® Visio and Microsoft® Excel. VMGSim provides accurate, robust and cost effective steady state process simulation software to predict the detailed behaviour of process units and manufacturing plants. Whether designing new process units, optimizing or troubleshooting, VMGSim assists engineers to improve operating efficiency and product quality, realize objectives of reduced capital and operating costs, greater safety and increased profitability. The capabilities of VMGSim enable you to accurately model and predict the behaviour of most process units in Oil and Gas, Refining and Petrochemical industries. VMGSim brings new innovations that streamline development and use of simulation models:
The
Simulation Engine VMGSim can solve even your largest models with no limits on flow sheet units, pure components or recycles. You can create process models and store these models as unit templates and then reuse them in new process models. The subflowsheet architecture of VMGSim also enables you to embed these templates called subflowsheets at any degree of nesting in the process scheme. Advanced calculation techniques in VMGSim are ideal for successfully modelling your process. The VMGSim technique simplifies your models. Heat recycles are eliminated. There is no need to include unreal streams in the process model because these are eliminated by the unique port-to-port connectivity, integral to the design of the flow sheet engine. VMGSim also automatically determines any recycle loops in the model and solves without intervention. Calculations proceed as data is provided and they proceed forward or backward depending on the information supplied. Automatic determination of flow sheet degrees of freedom ensures your models are not over specified. Every piece of information you enter into VMGSim is processed immediately in a fashion similar to spreadsheet software products. As a result, models are developed and optimized quickly. Thermophysical Properties System VMGSim provides a comprehensive suite of critically evaluated data for over 5,500 pure components, and a mixture interaction parameter database of over 100,000 binary parameters. For oil refining models, VMGSim incorporates an extensive system for evaluating assay data and characterizing refining streams. Industry specific physiochemical properties such as hydrate formation temperature, Reid vapour pressure, Research Octane Number and Cetane Index can be calculated and monitored. Robust industrial strength thermophysical property methods and equilibrium flashes reliably converge to accurate results. Process models that require multiple thermophysical methods are easily supported. Process Unit Operations VMGSim includes a complete suite of process unit models for example:

A critical step in the
design of a chemical process is the accurate simulation thereof.
Having recently been appointed as the sole Southern African agents of
the state of the art simulation package VMGSim, SimPro engineers have
the latest in software technology available to them. This enables us
to simulate and design processes to the highest standard current
technologies allow.
