The water content of a carbon dioxide (CO{sub 2})-rich phase containing 5.31 mol % methane (CH{sub 4}) and balance CO{sub 2} In equilibrium with a water-rich phase was measured above the initial hydrate formation conditions and at isobars of 6.21, 7.59, 10.34, and 13.79 MPa, or of 900, 1100, 1500, and 2000 psia, respectively, at temperatures ranging from 15.6{degrees} C (60{degrees} F) to 50.0{degrees} C (122{degrees} F). The measurements indicated that the presence of 5.31 mol % methane in CO{sub 2} lowered the water content value by 20-30% from that of pure CO{sub 2}. The water content of the mixture is superimposed on the pure CO{sub 2} data for comparison. In this paper, the relevant water content data are presented in both tabular and graphical forms.
