Influence of Sodium Chloride on the Formation and Dissociation Behavior of CO₂ Gas Hydrates.

ABSTRACT: We present an experimental study on the formation and dissociation characteristics of carbon dioxide (CO₂) gas hydrates using Raman spectroscopy. The CO₂ hydrates were formed from sodium chloride/water solutions with salinities of 0-10 wt %, which were pressurized with liquid CO₂ in a stirred vessel at 6 MPa and a subcooling of 9.5 K. The formation of the CO₂ hydrate resulted in a hydrate gel where the solid hydrate can be considered as the continuous phase that includes small amounts of a dispersed liquid water-rich phase that has not been converted to hydrate. During the hydrate formation process we quantified the fraction of solid hydrate, x_H, and the fraction of the dispersed liquid water-rich phase, x_L, from the signatu
