Build Any Mill in Python: A Modular Simulation Platform for Pulp & Paper
Python-based mass, energy, and water balance for any pulp & paper mill configuration
About
About the Book
Every pulp & paper feasibility study starts the same way: a blank
spreadsheet, hardcoded mass balances, and weeks of debugging.
Modular Mill is a Python platform that changes this. Assemble any
mill configuration from LEGO-like process modules — OCC, Kraft,
Board Machine, Tissue Machine — connect them, call mill.run(),
and get automatic mass, energy, and water balance instantly.
What's inside:
- 8 production-grade modules validated against industry design data
- Physics-based dryer models (TAPPI DR curves, Yankee evaporation)
- Recovery boiler, turbine, and power strategy simulation
- Operating cost layer with sensitivity analysis
- Interactive Streamlit dashboard
- 2,414 automated tests — all passing
No NumPy, no SciPy. Standard library only in the calculation engine.
This is a living book. All future updates — new modules, deeper
physics models, additional mill examples — are delivered free to
all buyers automatically via Leanpub.
