how to convert CO2(g) to CO2(aq) and H2S(g) to H2S(aq)

[XiaoMao]

I have run my model which describes a process of injection of mixed gases.

However, I only get the results of CO2(g), H2S(g). How can I convert them form gas to aqueous? I wish I can get the result of CO2(aq) and H2S(aq).

Unfortunately, aqueous complexes were not output in TOUGHREACT v1.2, which is the version of TOUGHREACT that is packaged with PetraSim.  This feature was added in later versions of TOUGHREACT.  You might consider purchasing TOUGHREACT v3.3, which is available through LBL.  PetraSim creates input files for TOUGHREACT v3.3.  We hope to add better support with result visualization in the future.

OH, can I calculate them by myself ?

CO2, H2S and H2 consist of mixed gases. They are injected into my model.

I can get them CO2(g), H2S(g), and H2(g), so can I calculate by some method to convert them to aqueous?

Hello:

 

You can manually titrate gases into solution using a program such as PHREEQC or The Geochemist's Workbench via reaction path model. This should calculate your dissolved concentrations.

 

Hope this helps,

wa, Tom

Thanks a lot

I will try to convert it by gwb.

I am doing some model by gwb..

Thansk again.
