“…Therefore, it was possible that muscle tissue acted as the micro-filter and cell membranes play its role as the nano-filter, similar to the micro-filter used in Ishikawa et al 2014. Smaller bubble size of scCO increase its solubility and dissolution rate in pure water was reported by Suzuki et al (2013). Higher dissolved CO is expected to yield higher inactivation of enzymes, since it increase the availability of CO for altering secondary structure of the enzyme.…”

The studies of the effect of supercritical carbon dioxide (scCO2) pasteurization on solid food from fish origin are scarcely available. This study was intended to address that gap by investigating the effect of scCO2 on the reduction of muscle protease activity and its impact on physicochemical properties of the Nile tilapia. Tilapia were exposed to CO2 pressure at 70, 75, 80, 85, and 90 bar; temperature at 40 °C; and holding time for 15 min. This study discovered that 80 bar was the minimum pressure to achieve half residual activity of muscle protease and two logs reductions of microbial counts. The applications of 80 and 85 bar were found to achieve significant reduction of tilapia muscle protease activity while still maintained acceptable textural properties. Both 80 and 85 bar were found to be effective to inhibit softening development of tilapia fillet during 14 days of chilled storage. Eighty-five bar and 15 min CO2 pasteurization was considered as maximum level of CO2 pressure that tilapia could withstand without degrading its texture significantly.

“…More so, technologies aimed at utilizing the emitted greenhouse gases are also being developed. 3 One such technology includes the capture, storage, and utilization of CO 2 . Of the alternatives available that include the bulk storage of CO 2 in subsurface reservoirs, the formation of flue gas hydrates, 4,5 and utilization of the CO 2 for mineralization, the latter is considered most widely and continues to receive attention in recent times.…”

The reduction of carbon footprints is one of the steps being taken as the world looks for a solution to the difficulties caused by climate change. This will be accomplished by developing technologies that both consume and emit less carbon dioxide into the atmosphere. Other methods include mineralization or bulk storage of the captured gases in subsurface reservoirs. Mineralization involves the interaction of cation-rich rocks or fluids with carbonated water to form precipitates that ensure the safe disposal of CO2 that has been captured. To assess the viability of this route, numerous initiatives have been made as well as a few experimental projects. Understanding of the electrokinetic property of igneous rocks, which governs characteristics like wetting conditions and susceptibility to release cations, is, however, rare in the literature. Thus, to shed light on the electrokinetic behavior and colloidal stability of igneous rocks, this research has employed electrophoresis. This research revealed that igneous rocks are mainly negatively charged in both freshwater and saltwater environments. On the other hand, igneous rocks’ magnesium ion content significantly affects how they are charged, occasionally flipping the charge to positive and shifting the solution state from acidic to alkaline. This would have an even greater effect on the mineralization process and shorten the time needed for the reaction between igneous and CO2-rich fluids. This is inferred by the fact that the highest dissolution of metal cations is known to occur at pH values of 3 and 4. Furthermore, samples with a low magnesium content have stable colloidal stability, whereas samples with a high magnesium content are colloidally unstable. The samples’ colloidal stability also has a significant impact on how easily the cations needed for mineralization are released.

“…Zankoor et al [9] achieved a geometric analysis of the fluid-fluidrock interface at the pore scale by in-situ capillary pressure and wettability, which showed an agreement between the image-based capillary pressure and macroscopic measurements in multiphase flow. Jahanbakhsh et al [10] demonstrated that heterogeneous wettability had an impact on fluid interface evolution and displacement patterns. There are various studies to investigate the influence of wettability on oil recovery.…”

CO2-EOR (Enhanced Oil Recovery) is a vital method to increase oil recovery while significantly lower greenhouse gas emissions. The near-miscible conditions are useful to improve displacement efficiency and oil recovery by CO2 injection. In this study, at the nearmiscible condition of 8MPa, 40°C, using X-ray microtomography (micro-CT), pore-scale interfacial characteristics can be obtained in the CO2-oil-glass beads system, such as wettability, which represents the tendency of fluids in the solid. A displacement of oil by CO2 was performed to examine the two-phase interfacial characteristics in the gas-oil-solid system. With the multiphase identification approach and in-situ spatial distribution of contact angle (𝜃𝜃), the 𝜃𝜃 at 5.5PV was nearly 66.99° at near-miscible conditions, which indicates an intermediate-wet system. With increasing injection pore volumes (PV) from 5.5PV to 16.4PV, the contact angle increases from 66.99° to 70.42°, indicating a decrease in the water-wet property. Although oil resides in pores of all sizes (big, medium, and small), gas often fills the larger pores. The interfacial curvature examination revealed that in-situ capillary pressure provides a distribution with an average value near zero. The rock performed a wettability reversal from a waterwet to an intermediate-wet condition. The knowledge of near-miscible two-phase flow is helpful to enhance oil recovery and storage efficiency.
