    摘要: Techniques for growing crystalline calcium carbonate solids such that the crystalline calcium carbonate solids include a volume of 0.0005 mm3 to 5 mm3, include a slaker to react quicklime (CaO) and a low carbonate content fluid to yield a slurry of primarily slaked lime (Ca(OH)2); a fluidized-bed reactive crystallizer that encloses a solid bed mass and includes an input for a slurry of primarily slaked lime, an input for an alkaline solution and carbonate, and an output for crystalline calcium carbonate solids that include particles and an alkaline carbonate solution; a dewatering apparatus that includes an input coupled to the crystallizer and an output to discharge a plurality of separate streams that each include a portion of the crystalline calcium carbonate solids and alkaline carbonate solution; and a seed transfer apparatus to deliver seed material into the crystallizer to maintain a consistent mass of seed material.

    摘要: Enhancing growth of algae in an algaculture facility includes contacting a growth medium with a gas including carbon dioxide, transferring some of the carbon dioxide to the growth medium to yield an enriched growth medium, and providing the enriched growth medium to the algaculture facility. The concentration of dissolved carbon dioxide in the enriched growth medium exceeds the concentration of dissolved carbon dioxide in the growth medium, where dissolved carbon dioxide includes ions formed by the reaction of carbon dioxide with a species in solution. The growth medium may be obtained from the algaculture facility, and may be filtered or otherwise processed before or after contacting the growth medium with the gas. Providing the enriched growth medium to the algaculture facility increases the concentration of dissolved carbon dioxide in the bulk growth medium of the algaculture facility.
