Bosen-Engels approach for electrolyte fluids

The Bosen-Engels approach for electrolyte fluids relies on a specialized configuration for the Fluid within AVEVA Process Simulation. It uses the same thermodynamic calculations as the NRTL method but uses an additional reaction submodel to include reaction equilibrium as part of the phase and composition calculations.

To use the Bosen-Engels approach, you need a thermodynamic library that contains the property data for the ionic and pure component species in your equilibrium reactions. The default SimSci library should contain the required data for the pure component species, but you may need to create a custom library with custom data banks that include binary interaction data and component properties for all ionic species. See Manage thermodynamic libraries and Create a custom thermodynamic library from PPDX data for more information.

To use the Bosen-Engels approach, you also need a reaction submodel that defines the reaction kinetics of your system. Typically, this includes equations for the rate constant and the reaction rates that you develop from empirical data for the reaction system. See Reaction submodels for the Bosen-Engels approach for more information.
