I have two question
1- Regarding temperature dependency of Henry's coefficient, I was wondering if TOUGH2/EOS7C considers this or not? and if yes, at what reference temperature should HCTRC (SELEC.7) be put as an input? (maybe you can also give me hints where I can find this temperature dependency within the source code?)
2- Is phase-partitioning calculated only for equilibrium conditions?
Many thanks in advance,
1. See the EOS7C User's Manual, Section 2.2, in particular, the text leading up to Equation (13), which describes how the Henry's coefficient is calculated for the NCG component (component #3), which can be CO2 or N2. It is temperature dependent. The SELEC.7 entry is the inverse Henry coefficient for the tracer component (component #4), which is just a constant.
2. TOUGH always assumes local equilibrium, so phase partitioning always applies. Maybe I am misunderstanding your question, so if anyone else has something to add here, please do.
