Thermodynamic Modelling and Experimental Study of Hydrate Formation in CO2-Rich Systems
Project abstract
This research focuses on the thermodynamic modelling and experimental investigation of hydrate formation in CO₂-rich systems under high-pressure conditions. The study examines hydrate phase equilibria, dissociation behaviour, and the influence of gas composition, salinity, and chemical additives on hydrate stability. Experimental measurements are conducted using a High-Pressure Isochoric Hydrate Cell (HP-IHC) to generate reliable equilibrium data across controlled temperature and pressure ranges. The experimental results are integrated with advanced thermodynamic modelling approaches based on the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) coupled with the van der Waals–Platteeuw hydrate model. Attention is given to the representation of molecular association, hydrogen bonding, and non-ideal interactions in multicomponent CO₂-rich mixtures. The work further evaluates the effects of electrolytes and alcohol-based inhibitors on hydrate suppression and equilibrium shifts. The validated modelling framework is expected to improve the prediction of hydrate phase behaviour in complex fluid systems and provide experimentally supported thermodynamic data for hydrate equilibrium studies and flow assurance applications.
