Abstract
In some embodiments, the invention provides, a method comprising a) contacting a solution with an industrial source of carbon dioxide to produce a CO2-charged solution; b) subjecting the CO2-charged solution to conditions sufficient to produce a composition, wherein the composition comprises carbonates, bicarbonates, or carbonates and bicarbonates; c) separating a supernatant from the composition; and d) recirculating at least a portion of the supernatant for contact with the industrial source of carbon dioxide. In some embodiments, the invention provides a system comprising a) a processor configured to produce a composition from an industrial source of carbon dioxide, wherein the composition comprises precipitation material comprising carbonates, bicarbonates, or carbonates and bicarbonates and a treatment system configured to separate a supernatant from the composition, wherein the processor and the treatment system are operably connected for recirculation of at least a portion of the supernatant.

65. A method comprising:
-
a) contacting a solution with an industrial source of carbon dioxide to produce a CO2-charged solution; b) subjecting the CO2-charged solution to conditions sufficient to produce a composition comprising carbonates, bicarbonates, or carbonates and bicarbonates; c) treating the composition to produce a concentrated composition, wherein treating the composition comprises 1) dewatering the composition to increase the concentration of carbonates, bicarbonates, or carbonates and bicarbonates in the resulting concentrated composition and to simultaneously produce a supernatant and 2) filtering the supernatant to produce a filter stream; and d) providing at least a portion of the filter stream to an electrochemical process for producing proton-removing agents.
