1. An apparatus comprising:
a fluidized bed vessel that comprises a housing and an inner volume;
a distribution plate mounted in the inner volume to separate the inner volume into a top volume portion and a bottom volume portion below the top volume portion;
one or more first inlet ports arranged in the housing to supply to the top volume portion at least one feed stream comprising at least one of calcium oxide, calcium carbonate, or water;
one or more second inlet ports arranged in the housing supply a fluidization gas into the bottom volume portion;
a fluidization zone defined in the top volume portion of the inner volume above the distribution plate and configured to:
receive the fluidization gas from the one or more second inlet ports through the distribution plate;
receive the at least one feed stream from the one or more first inlet ports into the top volume portion, and
generate a fluidization velocity in the inner volume that fluidizes and separates at least a portion of the calcium carbonate and at least a portion of the calcium oxide into a fluidization regime in the top volume portion;
a cyclone fluidly coupled to a feed port of the housing, the cyclone configured to separate a portion of the fluidization gas from a portion of at least one of a calcium hydroxide, the calcium carbonate, or the calcium oxide; and
at least one discharge port arranged in the housing above the distribution plate and below the feed port, the at least one discharge port configured to discharge a portion of at least one of the calcium hydroxide, calcium carbonate or calcium oxide from the inner volume.
