Abstract

CO 2 hydrate formation and dissociation is crucial for hydrate-based CO 2 capture and storage. Experimental and calculated phase equilibrium conditions of carbon dioxide (CO 2 ) hydrate in porous medium were investigated in this study. Glass beads were used to form the porous medium. The experimental data were generated using a graphical method. The results indicated the decrease of pore size resulted in the increase of the equilibrium pressure of CO 2 hydrate. Magnetic resonance imaging (MRI) was used to investigate the priority formation site of CO 2 hydrate in different porous media, and the results showed that the hydrate form firstly in BZ-02 glass beads under the same pressure and temperature. An improved model was used to predict CO 2 hydrate equilibrium conditions, and the predictions showed good agreement with experimental measurements.
