Abstract

The solubility of water in the CO₂-rich phase was measured in the presence of hydrate using an indirect method at the temperatures ranging from (274 to 294) K and pressures of (6.1 and 10.1) MPa. The experimental data set of Song and Kobayashi (SPE Form. Eval.1987, 2, 500-508) was previously reported for this system, and a large pressure dependence was observed at the pressures of (6.21 and 10.34) MPa. The present solubility data were compared with published experimental data at the hydrate-free region. A weak pressure dependence was observed compared with the data of Song and Kobayashi in the present measurements.
