VMGSim is a general process simulator and possesses a complete suite of process unit operations which can be configured to model virtually any process in the Gas processing, Refining/Petrochemical or Chemical industries.
VMGSim includes a comprehensive suite of process unit models for example:
- Distillation - rigorous, robust and fast two and three phase distillation including complex refinery configurations and heterogenous azeotropic distillation
- Two- and Three-phase separators with multiple feeds and energy input
- Mixers, Tees, Component Splitters
- Balances - Mole, Mass and Energy balance operations
- Excel Embedded operations
- Pumps, compressors, expanders with option to input curves
- Control valves and relief valves
- Multiphase pipe operation
- Shell/Tube exchanger operation with rating from HTRI or STX
- Multistream exchangers
- CSTR, PlugFlow, Equilibrium, Gibbs and Stoichiometric Reactor models

- Embedded Equipment Rating and Design Third Party Applications
Rigorous tray by tray complex column
VMG features a very fast and robust column algorithm that has been carefully tuned to reliably converge on difficult complex refining distillation columns. The tower support two and three phase distillation and conveniently handles Side strippers, Pump arounds, heaters/coolers and multiple product and water draws. The tower has a full range of specifications and trays can be designed or rated.
