A Helmholtz energy equation of state with independent variables of temperature and density was developed for sulfur dioxide (SO 2 ) based on thermodynamic property data from the literature. The equation of state is valid from the triple-point temperature of 197.7 to 525 K, with pressures up to 35 MPa and densities up to 25.4 mol·dm −3 . The uncertainties in density of the equation of state are 0.1% in the liquid phase, 0.25% in the vapor phase, and 1% in the critical region. The uncertainty in vapor pressure is 0.2% and the uncertainty in saturated liquid density is 0.2% below 410 K. The uncertainty in isobaric heat capacity is 2% between 200 and 290 K. In the critical region, the uncertainties are higher for all properties except for vapor pressure. The behavior of the equation of state is correct not only within the region of validity, but also at high temperatures and pressures, and far below the triple-point temperature.

“…Before performing the main experiments listed in Table 2, a experimental conditions, CO 2 and SO 2 were at the supercritical [9] and liquid 207 states [58], respectively. We used a brine with 36500 ppm NaCl and 50000 208 ppm NaI salt concentrations as well as highly pure CO 2 and SO 2 gases for 209 the flow tests.…”

In this study we performed three categories of steady-and unsteady-state 8 core-flooding experiments to investigate capillary trapping, relative perme-9 ability, and capillary pressure, in a scCO 2 +SO 2 /brine/limestone system at 10 elevated temperature and pressure conditions, i.e., 60 • C and 19.16 MPa. We 11 used a Madison limestone core sample acquired from the Rock Springs Uplift 12 in southwest Wyoming. We carried out two sets of steady-state drainage-13 imbibition relative permeability experiments with different initial brine sat-14 urations to study hysteresis. We found that the final scCO 2 +SO 2 drainage 15 relative permeability was very low, i.e., 0.04. We also observed a rapid re-16 duction in the scCO 2-rich phase imbibition relative permeability curve, which 17 resulted in a high residual trapping. The results showed that between 62.8% 18 to more than 76% of the initial scCO 2 +SO 2 at the end of drainage was 19 trapped by capillary trapping mechanism (trapping efficiency). We found 20 that at higher initial brine saturations, the trapping efficiency was higher. 21 The maximum initial and residual scCO 2-rich phase saturations at the end 22 of primary drainage and imbibition were 0.525 and 0.329, respectively.
