CCsphase

In order to realize large scale carbon capture and storage (CCS), improved understanding of the behaviour of the fluids involved is required. The CCSphase project aims to fill knowledge gaps with regards to phase equilibria and transient phase behaviour for fluid mixtures and pressure and temperature states relevant for CCS. The project will include both experimental work and modelling to improve the prediction of phase behaviour. At SINTEF Energy Research (SINTEF ER), accurate phase equilibrium data for CO₂ and H₂ mixtures as well as mixtures involving water relevant for CCS will be measured using a setup designed specifically for CCS fluids. At Institute of Thermomechanics of the CAS, v. v. i. (IT CAS), transient behaviour of the same mixtures as well as the CO₂-N₂ system will be experimentally studied with a highly instrumented expansion chamber using optical characterization. In this setup, metastable states and nucleation occurring during a rapid pressure drop will be investigated. In a collaborative effort, both SINTEF ER and IT CAS will develop models for transient and equilibrium phase behaviour of CO₂ rich mixtures. The equilibrium properties will be modelled by adjusting parameters of the equations of state for the fluid phases and parameters of molecular based hydrate models. Nucleation processes will be modelled by modified classical nucleation theory and density gradient theory. The experimental data obtained in the project will be used to verify and improve these models. In addition to being an enabler for CCS as a part of the solution to avoiding a detrimental anthropogenic climate change, CCSphase is expected to produce large synergies between the partners both in the experimental work and modelling.
