Dissolution of gas in brine

Hi,

 

There are a number of ways to approach this problem. You might start out by using Rxn to balance dissolution reactions, and calculating the equilibrium constant at various temperatures. Creating simple activity diagrams with Act2 or Tact is quick and easy, but can be very helpful. Finally, you might use React to construct a reaction path model of gas dissolution into a brine. You'll probably want to familiarize yourself with some concepts from the Geochemical and Biogeochemical Reaction Modeling textbook, or the GWB User's Guides. I would look into simple titration models, and sliding fugacity and polythermal runs, for example. If you're using GWB 9, you might be interested in gas transfer kinetics as well.

 

If you go to our diagrams webpage, you'll see a number of example models calculated using Act2, Tact, and React. Take a look at some of these, including the "gas solubility" and "heating and cooling" examples.

 

Hope this helps,
