Transport and Cation Exchange
Overview
This benchmark simulates the chemical composition of the effluent from a column containing a cation exchanger (Example 11 in the PHREEQC 3 documentation). The following setup is used for the simulation:
Model setup for the simulation of the column with a cation exchanger in OGS6.
Full details of the model setup and parameters are given in the PHREEQC3 example (consulted MAY-2021):
The benchmark uses the ComponentTransport process in OGS-6 coupled with the IPhreeqc software (Parkhurst et al. 2013). The results show good agreement between codes. More details about the implementation of the ComponentTransport process in OGS-6 can be found in HC-Process.pdf.
Comparison between PHREEQC and OGS6 of simulated concentrations of solutes at time = 18,000 s reacting with an exchanger.
