Pressure-Mole Fraction Phase Diagrams for CO_2-Pure Water System Under Temperatures and Pressures Corresponding to Ocean Waters at Depth to 3000 M

摘要

Pressure-mole fraction phase diagrams for CO_2-water system at temperature peratures between 278.15 and 298.15 K and pressures up to 30 MPa, which correspond to those of ocean waters at depths to 3000 m, are developed based on the literature data and experimental results obtained by the authors. The resultant phase diagrams can serve as a basis for analyzing the phase behavior of liquid CO_2 and CO_2 hydrate disposed of in the ocean as a means to mitigate global warming.
