Walkthrough notebook

The OpenPyTEA walkthrough notebook is a self-contained Jupyter notebook that covers the full workflow end-to-end — equipment costing, plant configuration, financial calculations, sensitivity analysis, and result export — with live code, outputs, and explanatory text. It is the recommended starting point before reading the individual guide pages.

• Equipment Cost Estimation
• Plant-Level TEA
• Analysis
• Plotting
• JSON Workflow

Overview of the workflow

A typical OpenPyTEA study follows five steps:

1. Equipment costing  →  Equipment objects with purchased/direct costs
2. Plant configuration →  Costs, financial parameters, products, OPEX
3. Calculate           →  NPV, IRR, ROI, levelized cost, cash flows
4. Analyse             →  Sensitivity, tornado, Monte Carlo
5. Export              →  JSON results, publication-quality figures

Each step maps to a module:

Module	Key objects	Description
openpytea.equipment	Equipment	Equipment-level cost estimation with CEPCI inflation adjustment
openpytea.plant	Plant	Plant-level CAPEX, OPEX, and financial analysis
openpytea.analysis	Functions	Sensitivity, tornado, and Monte Carlo analysis
openpytea.plotting	Functions	Matplotlib-based publication-quality visualizations
openpytea.io	Functions	JSON configuration loading and result export
