Pytzer

Pytzer is a Python implementation of the Pitzer model for chemical activities in aqueous solutions [P91] plus solvers to determine the equilibrium state of the system.

Pytzer is in beta! Use at your own peril.

Installation

For general use

Install with pip (any OS):

pip install pytzer

On Mac or Linux, you can alternatively install from conda-forge:

conda install conda-forge::pytzer

However, the above will not work on Windows, because jax is not on conda-forge for Windows - so use pip instead.

Once installed, you will need to set the environment variable JAX_ENABLE_X64=True. For example, using conda:

conda env config vars set JAX_ENABLE_X64=True

Documentation
