GNNePCSAFT CLI

Project focused in the use of graph neural networks to estimate the pure-component parameters of the Equation of State ePC-SAFT.

The motivation of this work is to be able to use a robust Equation of State, ePC-SAFT, without prior need of experimental data. Equations of State are important to calculate thermodynamic properties, and are pre-requisite in process simulators.

Currently, the model takes in account only the hard-chain, dispersive and assoc terms of ePC-SAFT. Future work on polar and ionic terms are being studied.

Code is being developed mainly in Pytorch (PYG).

You can find the model deployed at GNNePCSAFT Webapp.

A CLI to use the model can be found at GNNePCSAFT CLI and installed with pipx or uvx:

pipx install gnnepcsaftcli
gnnepcsaftcli pred

uvx gnnepcsaftcli pred
