Recovering a caustic solution via calcium carbonate crystal aggregates: United States Patent 9975100

By: Heidel, Kenton Robert

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).sub.2); and reacting the Ca(OH).sub.2 slurry and the alkaline carbonate solution to grow calcium carbonate (CaCO.sub.3) crystal aggregates of 0.0005 mm.sup.3 to 5 mm.sup.3 in volume in a fluidized-bed reactive crystallizer.
