Design and sustainability analysis of a combined CO2 mineralization and desalination process

Testing and scaling-up of a novel Ti/Ru0.7Ti0.3O2 mesh anode in a microfluidic flow-through reactor

“…It means that the negative effect (which initially could be expected because of the less uniform coating with the enlargement in the electrode from the typical lab-size to a pilot-scale) is not observed with this novel method of preparing the anodes. Besides, the optimized design of the cell has led to an improved behavior associated with a better fluid-dynamics, as it was stated in previous works using this novel type of cells [39].…”

“…As a result of all reactions occurring, NaOH is accumulated (Eq. ( 13)), which is responsible for turning the medium alkaline with the time [39].…”

Lab on a chip for a low-carbon future

“…For example, the combination of water desalination with carbon storage through ex situ CO 2 mineralization 15 has been proposed to mitigate the impact of the technology and increase its sustainability. [225][226][227] Indeed, the waste brine generated through desalination is a potential source for CO 2 mineralization, because in brine the concentration of divalent cations (i.e., Ca 2+ and Mg 2+ ) necessary for binding CO 2 into stable minerals, is almost twice that of ordinary seawater. For instance, the process proposed by Oh et al (2018) 225 can achieve up to 230 tonne CO 2 reduction per year in addition to an economical benefit of water desalination.…”

However, the precipitation kinetics of carbonate minerals changes with brine composition and an intense experimental activity is required to determine the rates.…”

Integrated Process of Monoethanolamine-Based CO2 Absorption and CO2 Mineralization with SFGD Slag: Process Simulation and Life-Cycle Assessment of CO2 Emission

“…Concentrated CO 2 would be released with absorbent regeneration, while only partial concentrated CO 2 might be further utilized as a raw material for other industrial manufactures. CO 2 mineralization, proposed to convert gaseous CO 2 into solid carbonates with calcium or magnesium raw materials, is regarded as a potential technology to realize large-scale CO 2 fixation. , Various CO 2 mineralization technologies have been developed, including alkaline or nonalkaline ore or industry waste. − Due to physical or chemical stability of the ore or industry waste, the mineralization rate of direct exploitation is low. The raw materials should be usually activated at first. − …”
