Welcome to Clapeyron! This module provides both a large library of thermodynamic models and a framework for one to easily implement their own models.

The official manuscript is in ACS. https://pubs.acs.org/doi/10.1021/acs.iecr.2c00326. There is also a preprint available at arxiv: https://arxiv.org/abs/2201.08927

We have also presented at the JuliaCon 2021 conference! Feel free to take a look at our talk:

We support many equations of state and properties. Some examples of figures you can create are shown below:

• Isobaric heat capacity of carbon dioxide at 20 MPa:

  

• Water VLE envelope:

  

• Ethanol+water Pxy diagram at 423.15 K:

  

• pT-isopleth of methanol+cyclohexane generated using PC-SAFT:

If you find any issues, feel free to contact us directly on the Zulip Channel, or open a Github issue.

Installing Clapeyron

The minimum supported version is Julia 1.10. To install Clapeyron, launch Julia with

> julia

Hit the ] key to enter Pkg mode, then type

Pkg> add Clapeyron

Or to add the development version:

Pkg> add https://github.com/ClapeyronThermo/Clapeyron.jl#master

Exit Pkg mode by hitting backspace.

Now you may begin using functions from the Clapeyron library by entering the command

using Clapeyron

To remove the package, hit the ] key to enter Pkg mode, then type

Pkg> rm Clapeyron

Installing Clapeyron in Python

Clapeyron.jl is also available in python via the pyclapeyron package. You can install pyclapeyron from PyPI via pip or uv:

pip install pyclapeyron

or

uv add pyclapeyron

Package in active Development

Note that at its current stage, Clapeyron is still in the early stages of development, and things may be moving around or changing rapidly, but we are very excited to see where this project may go!

We are open to contributions. New models, improved methods and more databases are always appreciated!
