ProMax® is the leading software for modeling acid gas removal systems. Building on almost 50 years of simulation experience, ProMax offers the highest degree of accuracy, ease-of-use, and flexibility available today. ProMax contains all of the prerequisites for predictive simulation of these units out-of-the-box, including advanced thermodynamics, specialized distillation column modeling, and refined chemical reaction kinetics. User Defined customizations are also available.
ProMax offers the most comprehensive suite of generic and proprietary amine-based solvents on the market today.
MEA, DEA, TEA, AEE, MDEA, DIPA, any blend of amines with or without additives, degradation products, and heat stable salts
Huntsman DGA® Agent
Shell Sulfinol® (Special Request)
Along with amine-based solvents, ProMax can accurately model the performance of various physical solvent systems including DEPG, NMP, Methanol, and Propylene Carbonate.
ProMax’s Mass + Heat Transfer model provides rigorous and accurate predictions of contactors and regenerators. Integrated with excellent phase equilibria and physical property predictions, the Mass + Heat Transfer model provides superb predictions for a range of reactive and non-reactive systems. Simply put in the actual equipment in the design or operating unit and let ProMax do the rest!
The Mass + Heat Transfer model allows for the use of real trays for predictive results. Insert the exact number of trays in the model, the appropriate tray type (ex. valve, sieve), and the exact tray geometry desired.
ProMax includes a comprehensive offering of both random and structured packings, including those from major vendors such as Pall, Koch, Sulzer, Raschig, and others. A large selection of both random and structured packings are available by default. The user can insert their own custom packings as well. The Mass + Heat Transfer model will calculate the column hydraulics, including pressure drop and flooding, as well as mass and heat transfer between the phases throughout the column.
Whether the column internals contain trays, packing, or a combination of the two, the rate of chemical reactions of some components plays a critical role in mass transfer. To account for this, accurate and refined kinetics are required. ProMax contains kinetic rates for CO2 reactions in amine systems.
The foundation of any good simulator is accurate thermodynamics containing the latest VLE and VLLE data available. ProMax contains almost 50 years of engineering judgement, experience, and development in its proprietary Electrolytic-ELR model, which is updated constantly. The Electrolytic-ELR model is capable of handling any number of available amines, amino acids, additives, heat stable salts, and other components.
And while accurate phase equilibrium is important, accurate physical properties are also critical for calculating various unit operations, including heat exchangers, distillation columns, pipelines, and more. The Electrolytic-ELR model contains excellent predictions for heat capacities, viscosities, densities, thermal conductivities, diffusivities for these non-ideal systems.
The implementation of the Mass + Heat Transfer is comprehensive. While ProMax automatically provides recommended default selections, the user has additional options to choose from if they desire.

For developers of new solvents and equipment, ProMax is the go-to tool that provides the power and flexibility to implement new methods and ideas on your own. ProMax offers the following customizations that the user can implement directly, allowing the proprietary nature of the new developments to be kept in-house and secure:
While ProMax offers an expansive offering of default packing selections, the user can also describe their own packings and implement them for both hydraulic and mass transfer calculations.
Whether it is a new mass transfer correlation for typical internals, or a correlation for column internals that do not even resemble traditional trays and packing, ProMax allows the user to input their own mass transfer correlations. This provides ease of customization of calculating mass transfer coefficients while harnessing the full power of ProMax’s advanced column calculations, providing significant benefits to developers of new mass transfer equipment.
With the constant development of new solvents, users need a way to simulate new and proprietary components in a full, complete simulation. ProMax provides this with the User Defined Components feature. The user can insert components, phase equilibria, reactions, and even reaction kinetics into ProMax without the need to share or expose their intellectual property to BR&E.
