Modeling the Chemistry of Carbon Dioxide - Rich Phases with Impurities
Dense Phase CO2 Corrosion: Modeling the Chemistry of CO2 – Rich Phases with Impurities
- Objectives:
- - Model the solubility of So in CO2 - rich phases in order to predict whether solid So can drop out in transmission lines
- - Predict whether So can undergo reactions in the presence of water
- Chemical subsystems to be modeled
- - Pure So
- Volatility of pure So provides a baseline for its solubility in gas phase
- - So – H2O
- Solubility of So in H2O is important if an aqueous phase forms
- Model development requires considering the S0 – H2O system because the reference state for liquid-phase species is infinite dilution in water
- - Pure So
- So – CO2
- Solubility of So in CO2
