Impact of SO₂ on Alteration of Reservoir Rock with Ca-Deficient Conditions and Poor Buffering Capacity under a CO₂ Geologic Storage Condition

Figure 3

Changes in the concentration of cations during gas-water-rock experiments (green triangle = pure CO₂ case, red square = 0.1% SO₂ case, and blue rhombus = 1% SO₂ case) and changes in the concentration of cations in the modeling (green dashed line = pure CO₂ case, red dashed line = 0.1% SO₂ case, and blue solid line = 1% SO₂ case).
