VMGThermo™

20,000 chemicals library. 10 years of program refinement. Extensively validated.

VMG’s programmers improve VMGThermo’s capabilities every day. We’ve been working on it for over ten years. The result of our work is a thermophysical property calculator with the versatility to run virtually any processing application – from monitoring the performance of an engine or natural gas well to optimizing natural gas compressors throughout your well’s lifecycle, plus improving the safety of relief valves. VMGThermo powers VMGSim and many other custom software applications. Its well defined programming interface gives it the flexibility to be embedded in any process simulation software or engineering application.

Relentless testing using experimental data collected and evaluated at the VMG-sponsored Thermodynamics Research Centre in Boulder, Colorado has developed the most accurate predictor of phase equilibria and physical properties for many processes used in the oil and natural gas processing, refining, petrochemical and chemical industries.

VMGThermo is capable of accurately predicting the behaviour of complex combinations of chemicals. With more than 80 thermodynamic property packages, VMGThermo can model most of the process systems used in the natural gas, refining, petrochemical and chemical industries.

Multi-phase flash system

VMGThermo’s multi-phase flash system has a robust material balance and phase stability algorithm. It calculates the number of phases in your process as well as the composition, amount and physical properties of the materials in each phase at thermodynamic equilibrium. Our flash system reliably performs the basic calculations for steady-state process simulators such as VMGSim and dynamic process simulators such as VMGSim and IDEAS. Beyond process simulation, VMGThermo is continously validated, giving it the capablity to model a wide variety of systems out of the box. It is also configurable and able to handle different specifications for flash calculations. These features make it the property package system of choice for designing relief valves, compressors and on-line monitoring systems.

The source of VMG’s Thermodynamics data

The Thermodynamics Research Centre (TRC) focuses its work exclusively on collecting and evaluating the physical properties of fluids. It belongs to the National Institute of Standards and Technology (NIST), which belongs to the United States Department of Commerce. VMG was the first process simulation company to join NIST. Embedding proven TRC data into VMGThermo allows us to build exceptionally accurate virtual processing models.
