Development of an advanced modelling framework to describe the phase behavior of CO2+impurities.
Geological storage of CO2 is an increasingly important technology for reducing carbon emissions.
To design and operate CO2 injection and long‑term storage efficiently, it is essential to understand the phase behavior between injected CO2, in‑situ reservoir fluids, and the impurities typically present in captured CO2 streams (CO2+X).
However, the experimental measurement of all possible CO2+X mixtures in all possible conditions is practically inevitable. Thus, it is crucial to describe these properties accurately through thermodynamic models under a robust and reliable computational framework.
The specific tasks in this project include the thermodynamic modelling of the phase behavior in CO2+X systems.
Great emphasis will be given to the development of a computational framework capable of handling the formation of gas hydrates.
In addition, highly advanced models will be validated against hydrate phase equilibrium data to finalize the modelling-computational framework. Then, the model will be applied for dynamic simulations related to CO2 injection and storage.
