... based on a fugacity-fugacity framework designed for a hydrogen-brine system. In this framework, the Soave-Redlich-Kwong (SRK) Equation of State (EOS) was applied to calculate gaseous-phase fugacity, while Henry's law was used to estimate aqueous-phase fugacity. These EOS models were further rigorously...
