First-principles process models
Build process models from mass and energy balances, thermodynamics and kinetics, from one unit to a full-scale project.

Discuss this service“We need a model built from the ground up”
Some questions need a model that follows the physics of the plant, especially where history doesn’t cover the conditions you care about. We build these to the size the problem needs, from a single unit to a full-scale project.
A good fit when
- You need to study conditions the plant hasn’t run at
- You want a trusted base for surrogates, ROMs or optimisation
- You need a single unit modelled, or a full-scale build
How the work runs
Timing is a planning estimate, confirmed after the first stage.
| When | Work | You can review |
|---|---|---|
| Scoping | Define the boundary, level of detail and questions to answer | Agreed model specification |
| Build | Develop balances, thermodynamics, kinetics and equipment models | Reviewable model structure and assumptions |
| Calibrate | Fit uncertain parameters to plant data | Calibration report |
| Validate | Test on operating periods not used for calibration | Validation report and known limits |
| Handover | Document the model and train your team | Model, code and documentation |
What we need
- Process flow diagrams and equipment data
- Stream compositions and physical property data
- Operating data for calibration and testing
- The questions the model has to answer
What you keep
- Process model your team can run
- Documented assumptions and model structure
- Calibration and validation reports
- Recorded limits of the model
Agreed before we start
- Questions the model must answer
- Required accuracy on key outputs
- Operating range to cover
When we’d stop
If a simpler model answers the question, we’ll recommend it. We also pause if key design or operating data can’t be obtained.
