Strengths and trade-offs
BIOVIA COSMOtherm (COSMO-RS) — where it wins
- Predicts solubility across liquids, solids and gases
- Covers phase equilibria, partitioning, vapor pressure and pKa
- Offers graphical workflows and command-line batch processing
Where it doesn't
- Windows desktop deployment limits platform flexibility
- Contact-sales pricing makes cost assessment less direct
- Specialized thermodynamics scope is narrower than process simulation
ProMax — 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.
