Dear Denis,
there is no "ready to use" model for what you what to do.
The co2 tests assume brine with a constant salinity and thus do not
account for salt precipitation. Precipitation is only accounted for in
the 2pncmin tests and the biomineralization example.
You would need to replace "air" in the 2pncmin tests by "co2" or
simplify e.g. the biomin example to fit what you want to do. I am not
entirely sure what exactly to recommend you to do as I am not 100% sure
what you exactly want to do and thus can only give general answers to
general questions.
Could you write in a bit more detail what exactly you want to model and
then maybe we could also meet remotely to discuss, maybe this could then
resolve the points in question a bit more efficiently.
Best regards
Johannes

Dear, Dumux comunity
My name is Denis , I was exploring different Dumux applications for
CO2 storage, went through couple papers , but didn’t find information
about including the drying front into simulation, but even it was
mentioned that this behaviour was neglected. By mentioning dry-out
front I mean the continuous injection of dry scCO2 vaporizes the
remaining formation brine in the swept zone, which persistently
increases the concentration of dissolved salt. When the salt
concentration reaches the solubility limit, it precipitates out of the
brine. For example , as it is done in ECO2N module of TOUGH2 or it
was done in this paper (https://doi.org/10.3929/ethz-b-000410774
<https://doi.org/10.3929/ethz-b-000410774>), "A Numerical Model for
Formation Dry-out During CO2 Injection…”.
In the binary coefficients of BrineCo2 fluid system
all the solubilities are included, so from my understanding only right
EOS required and the precipitation can be modeled in the same way as
in 2pncmin model? Or could you please point me in the right direction?
I went through biomineralization example , but it is slightly
different. Sorry if my understanding is a little bit primitive. Thank
you in advance.
Kind regards,
Denis.
