Try something new

250 mmcsf/d natural gas processing facilities in Malaysia. 15 ppm purity specification in the production of fine chemicals in Japan. Bitumen solvent extraction refinery near Alberta’s oil sands. VMGSim is used around the world to model existing processes and to design new facilities from the ground up. At the heart of VMGSim is VMGThermo, our thermophysical property calculator capable of accurately predicting the behaviour of complex fluid mixtures. With over 20,000 chemicals, more than 80 thermodynamic property packages and hundreds of unit operations, VMGSim provides unparalleled model sophistication and precision. VMGSim performs all of the routine calculations to free up your time to tackle processing challenges creatively. The result: you’ll find innovative ways to maximize the value of the end product, while reducing operating costs and wasted material.

Moreover, VMGSim behaves like your own engineering advisor – propagating information, anticipating your questions and suggesting effective methods for model development and exploration. Better still, VMGSim requires only the smallest amount of information necessary to build your model based on rigorous thermodynamic relationships.

Real-time process calculations

VMGSim instantly calculates process changes, intelligently propagates information and continually monitors degrees of freedom when you modify any unit operation parameters or process conditions. This allows you to try many different equipment configurations within your virtual plant and see the effects of changes to the system instantaneously and inexpensively.

Bi-directional information propagation

VMGSim allows you to model plants using a relatively small number of inputs. It has the capability to extract the maximum amount of useful information from your data. Information is propagated throughout your flow sheet automatically, allowing you to develop creative solutions to extremely difficult problems you may not be able to easily solve using traditional sequential simulators. VMGSim tracks of all of your data inputs so you can see what was added to the system and the result immediately. VMGSim’s bi-directional information propagation capability also eliminates the need for artificial recycle blocks and simultaneous convergence of recycles and controllers throughout your flow sheet.

Automatic degrees of freedom monitoring

VMGSim is a true Gibbs-based simulator capable of monitoring each variable’s state and its significance from a thermodynamic point of view. If enough degrees of freedom are fulfilled according to the Gibbs phase rule, calculations are automatically completed and the results propagated throughout your flow sheet. VMGSim uses VMGThermo’s state of the art flash and property package systems for the utmost reliability when modeling natural gas, sweetening, sulfur treating and refining. Simulations are automatically recalculated every time you change the value of a variable without the need of special estimates. You concentrate on understanding your process while VMGSim handles the mathematics and physics.
