Petro-SIM 7.6: Process Simulation & Digital Twin Platform
Petro-SIM 7.6 is the latest version of KBC’s process simulation software for oil refining, petrochemicals, and sustainable fuel production. Released commercially on July 3, 2025, it features FTR-SIM for SAF production, advanced polymer modeling powered by Predici, new NOMAD solver for optimization, and enhanced assay work-up tools .
Key New Features in Version 7.6
New Reactor & Process Models
| Feature | Description |
|---|---|
| FTR-SIM (Fischer-Tropsch Reactor Model) | Simulates FT synthesis for Sustainable Aviation Fuel (SAF) production from syngas; rigorous heat/material balances; kinetic models for Cobalt and Iron catalysts; supports integration with downstream hydroprocessing for complete digital twin of sustainable fuel production |
| Advanced Polymer Modeling Powered by Predici | Predicts polymer properties, optimizes grade transitions, monitors catalyst impacts; supports cascading reactors, semi-batch reactors, detailed cooling jacket, activation volume reaction rate kinetics; includes polymer database with new components and updated physical transport/thermodynamics properties |
| Water Electrolyser Model | User can input polarization curves for different temperatures |
Optimization & Solver Enhancements
| Feature | Description |
|---|---|
| NOMAD Solver | New blackbox optimization solver for energy efficiency optimization, production planning, and emission reduction; solves difficult optimization problems where gradients are unavailable or unreliable |
| New Least Square Objective Function | For Optimizer module; default setup for minimization (replaces workaround based on cost/economics) |
| Calibration Tool for Pumps/Compressors/Expanders | New Calibration tab fine-tunes three scaling factors (Flow capacity, Head/discharge pressure, Efficiency/discharge temperature) using plant data |
| Base Delta Improvements | New in=out mode; publish/subscribe for multiple base delta solvers; fill EMPTY’s button for manual tables; non-linear expressions support (quadratic via variable cloning) |
