Clapeyron provides a framework for the development and use of fluid-thermodynamic models, including SAFT, cubic, activity, multi-parameter, and COSMO-SAC.

LVPP sigma-profile database + COSMO-SAC parametrizations

Thermodynamic Equations of State, Fortran library with both automatic and anallytical derivation capabilities

A Python library designed to swiftly and effortlessly obtain the UNIFAC-like groups from molecules by their names and subsequently integrate them into inputs for thermodynamic libraries. UNIFAC, PSRK, and Joback models are implemented.
