Our review
Pros
  • Rigorous heat, mass and energy balance calculations
  • Broad unit-operation and reactor models with physical-property libraries
  • Excel, specialist-tool and supply-chain assay integrations
  • 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.
Cons
  • Pricing requires a sales engagement
  • Focuses on steady-state process simulation
  • Specialist integrations and custom models may demand process expertise
  • 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.
