Web29 jul. 2010 · The interfacial tension between CO 2 and water σfl starts at ∼72 mN/m at 0.1 MPa and 295K and decreases linearly at a rate of ∼7 mN/m per MPa increase in CO 2 pressure until the liquid-vapor boundary is reached. Thereafter, the interfacial tension remains nearly constant at σfl ≈ 20–30 mN/m. WebIn order to perform the interfacial tensionmeasurement s, liquid drops (Pendant Drop) or gas bubbles (Bubble Rise) are created inside the cell at the tip of a capillary tube (o.d. ± 0.510 0.001 mm) and maintained at equilibrium in contact with the gas or aqueous phase, respectively, as depicted in Figure 1

WebThe interfacial tension (IFT) has an effect on capillary pressure and relative permeability, and thus affects the flow through capillary tubes of porous medium . Moreover, CO 2 and oil become completely miscible when the reservoir or injection pressure is above the minimum miscibility pressure (MMP), leading to the reduction of their IFT to zero [ 10 ].
