Activity coefficient models


The following activity coefficient models will be available in TP-Cloud:


Activity coefficient models are frequently used, with great success, to describe the thermodynamic properties of electrolytes in a liquid-phase 1. An advantage with this type of model, is that they have been used for a long time such that tried and tested parameters are available for many components and mixtures. We will implement the following activity coefficient models in TP-Cloud, e-NRTL and Extended UNIQUAC.

e-NRTL

Here, we will provide a more in-depth description of the activity coefficient model e-NRTL.

Extended UNIQUAC

Here, we will provide a more in-depth description of the activity coefficient model called extended UNIQUAC.
