摘要： An apparatus for accelerated dissolution of carbonates with buffered pH. The apparatus includes a mixer, a dissolution reactor and a pH correction reactor. The mixer includes: a chamber; a water supply; a carbonic gas supply; and a carbonate supply. Water, carbonic gas and carbonate are provided to the chamber in predetermined continuous flow rates to obtain a design flow rate of lean mixture at the outlet. The dissolution reactor includes a duct connected to the chamber receiving the lean mixture and allowing at least partial dissolution of the carbonate which transforms the lean mixture into an ionic mixture according to the reaction CaCO3+CO2+H2O□ Ca(HCO3)2. The pH correction reactor comprises a duct and a hydroxide supply. The mixture is then released into the sea. Embodiments also relate to a method for the accelerated dissolution of carbonates with buffered pH for the permanent sequestration of CO2 in the sea in the form of bicarbonates.
