Engineers’ CO₂ companion for CCS: phase plots, Joule–Thomson cooling checks, and metallurgy guidance—fast, clear, and built for real-world decision support.
The CCS Toolbox is a practical engineering companion for Carbon Capture & Storage and CO₂ transport projects. Built for engineers who need quick, defensible checks in the field or at their desk, it brings core CO₂ thermodynamics, phase awareness, and CCS-focused decision support into one clean, fast toolkit.
Key Capabilities
CO₂ Phase Plots & Thermodynamics
Explore pressure–temperature phase behaviour with clear visual plots.
Plot key operating points (e.g., arrival, wellhead, bottomhole) to quickly spot proximity to two-phase regions.
Use phase awareness to support safer, more robust decisions for compression, pipeline transport, injection, and shut-in scenarios.
Joule–Thomson Cooling & Temperature Drop Checks
Estimate JT cooling/heating trends for pressure changes in CO₂ streams.
Quickly assess where rapid depressurisation may drive temperatures toward hydrate/ice formation risk or materials constraints.
Useful for conceptual checks, operating envelopes, and “what-if” comparisons.
Metallurgy Guidance for CO₂ Service
CCS-specific support for materials selection thinking and corrosion risk awareness.
Consider common choices (carbon steel vs CRA options) in the context of CO₂ phase, impurities, water presence, and operating conditions.
Structured, engineer-friendly logic designed to complement—not replace—formal corrosion/materials studies.
Quick Calcs & Practical Utilities
Fast “back-of-the-envelope” calculators to support early design screening and operational troubleshooting.
Clear inputs/outputs, sensible units, and export-friendly results for sharing with colleagues.
Designed for Real Engineering Work
Fast, focused UI: fewer taps, less hunting.
Engineering-first presentation: charts, key points, and results that are easy to sanity-check.
Built to evolve: CCS Toolbox is a growing toolkit, expanding as new CCS workstreams and workflows demand.
Important Note
CCS Toolbox provides engineering calculators and decision support intended for screening and guidance. It is not a substitute for full project-specific engineering, verification, or regulatory compliance.
