Direct Aqueous Mineral Carbonation of Carbide Slag in a Bubble Column Reactor Under Ambient Conditions

Gas and slurry flow behaviors in a CO2‐mineralization spray tower reactor

“…To realize the high CO 2 absorption efficiency, many researchers have tried to apply different reactors, such as continuous tubular reactors, autoclave reactors, high-gravity rotating packed beds, and bubble columns. [16][17][18][19] But most of these reactors have high energy consumption, making them unsuitable for large-scale industrial applications. Different from them, the spray tower reactor with low cost, low pressure drop, and not easy to be clogged, 20,21 is ideal industrial mineralization equipment, thus it has been widely used in the treatment of sulfur-containing flue gas.…”

“…During the CO 2 ‐mineralization process, the type and performance of three‐phase reactors have played an important role. To realize the high CO 2 absorption efficiency, many researchers have tried to apply different reactors, such as continuous tubular reactors, autoclave reactors, high‐gravity rotating packed beds, and bubble columns 16‐19 . But most of these reactors have high energy consumption, making them unsuitable for large‐scale industrial applications.…”
