Abstract
Techniques for converting a portion of a carbonate to hydroxide include receiving an alkaline carbonate solution that includes between 0.1M (moles per liter of solution) to 4.0M hydroxide and between 0.1M to 4.1M carbonate; reacting, in a slaking process, quicklime (CaO) and a low carbonate content fluid to yield a slurry of primarily slaked lime (Ca(OH)); and reacting the Ca(OH)slurry and the alkaline carbonate solution to grow calcium carbonate (CaCO) crystal aggregates of 0.0005 mmto 5 mmin volume in a fluidized-bed reactive crystallizer.
