PRO/II 9.2

PRO/II is a steady-state process simulation software package developed by SimSci-Esscor for designing, analyzing, and optimizing chemical processes. Widely used in refining, petrochemical, chemical, and gas processing industries, it enables engineers to build process flow diagrams, perform heat and material balances, and rigorously model unit operations to support new designs, revamps, and debottlenecking studies.

Key capabilities include:

• Extensive thermodynamic methods and physical property databases for accurate phase and property predictions.
• Rigorous models for distillation (tray and packed columns), reactors (equilibrium and kinetic), heat exchangers, compressors/expanders, pumps, separators, and pipelines.
• Refinery-focused tools, including crude assay handling and petroleum fraction characterization for complex hydrocarbon systems.
• Scenario management, sensitivity analysis, and built-in optimization to evaluate what-if cases and improve process performance.
• Comprehensive reporting and equipment sizing to support engineering deliverables and decision-making.
• Integration with complementary SimSci tools to extend workflows from offline design through to operational improvement.

Engineers use PRO/II to reduce project risk, improve energy efficiency, and validate design choices with reliable, physics-based models.
