• Where it wins

  • Models acid-gas removal with amine solvents and reaction kinetics.
  • Connects models to PI, OPC-HDA, ODBC databases, and Excel.
  • Combines optimization with pipeline, corrosion, and emissions tools.

• Where it doesn't

  • Runs as a Windows desktop product, limiting platform options.
  • Uses contact-sales pricing rather than published plan tiers.
  • Its focus is process simulation, not chemical inventory or SDS management.

Our verdict on ProMax

ProMax is process simulation software from Bryan Research & Engineering for engineers in oil and gas, refining, treating, and related process industries. It is particularly suited to gas-processing teams working on acid-gas removal and other plant operations that benefit from detailed thermodynamics, reaction kinetics, and equipment models. The product is a Windows desktop application, with a stated fit for mid-market and enterprise organizations. It is a process-modeling tool rather than a system for chemical inventory or safety data sheet management, so teams looking for those workflows should consider a different category of software.

Its modeling breadth is concentrated on process engineering problems. ProMax covers amine-based acid-gas removal, caustic systems such as mercaptans removal and ethylene scrubbing, and pipeline networks. Equipment tools include depressurization and adsorber blocks, while separate analyses address corrosion and liquid-spill emissions. Optimization lets engineers define variables, constraints, and objective functions. This combination may suit teams that need to model connected aspects of gas treating and plant operations; organizations seeking a general-purpose chemical tool rather than process simulation may find the focus too narrow.

Data Exchange connects models with plant data sources and databases, including PI, OPC-HDA, ODBC-compatible databases, and Microsoft Excel. The vendor describes ProMax 7.0 as supporting real-time plant data connections, which gives it a role in workflows that link process models with plant information. Pricing follows a contact-sales model, rather than a published set of plan tiers, so procurement begins with the vendor. Support channels include email, phone, and documentation. ProMax is a plausible fit for engineering groups that need its specific process models, plant-data connections, and optimization; it is less suitable for teams that need another software category or a cross-platform deployment.
