Abstract Phase behavior and physical property measurements were carried out on mixtures of SO 2 ‐H 2 O; CO 2 ‐H 2 O, 5, 10, and 20 weight percent NaCl brines; and ternary CO 2 ‐SO 2 ‐H 2 O mixtures. The temperature was kept constant at 45°C, while saturation pressures were varied up to about 15 MPa. Binary measurements demonstrated that, at the same temperature and pressure, the mutual solubilities of SO 2 and H 2 O are higher than those of CO 2 and H 2 O. A three‐phase region has been identified in the termary CO 2 ‐SO 2 ‐H 2 O phase diagram at 7.24 MPa, but no such region was found at higher pressures.
