Objectives
What trainees will gain
- Calculate the speciation of an aqueous solution and simulate water–gas–solid interactions in open or closed systems.
- Model the evolution of a fluid's chemical composition with changes in temperature, pressure and salinity.
- Track the chemical composition of a fluid during the dissolution and precipitation of solid phases.
Content
What the programme covers
Foundations
- Principles of thermodynamics, the law of mass action, aqueous speciation and equilibrium.
- Concepts of concentration and activity, redox reactions, Pourbaix diagrams and bacterial activity, and thermodynamic databases.
Solution–mineral–gas interactions
- Mineral solubility and saturation indices, the Gibbs phase rule, reaction kinetics and disequilibrium, and surface complexation and ion exchange reactions.
Key factors and applications
- Effects of pH, temperature, pressure and salinity, and mixing of solutions.
- Applied cases: changes in groundwater chemistry during pumping, the partial pressure of carbon dioxide in equilibrium with a rock, bacterial denitrification, the biogeochemical behaviour of mine waste, and sorption of an organic molecule onto iron hydroxide.
