    Abstract: 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.

    IPC: B01D53/14 ,  B01D53/78

    Abstract: Techniques for humidifying a gas stream using a hydration system includes directing a gas stream through a contact zone of at least one hydration system; directing a hydration solution into the contact zone using a pump; contacting the gas stream with the hydration solution; evaporating water from the hydration solution into the gas stream to form a humidified gas stream, transporting the humidified gas stream out of the at least one hydration system; and collecting the remaining hydration solution in a hydration solution collection basin below the contact zone. The at least one hydration system is fluidly coupled to at least one downstream process and the humidified gas stream from the at least one hydration system is transported as a feed stream to the at least one downstream process.
