Abstract: A wastewater treatment system includes a circulating fluidized bed evaporator defining a longitudinal axis vertical with respect to gravity. The evaporator has a wastewater inlet to provide wastewater to the circulating fluidized bed evaporator. A heat inlet is axially below the wastewater inlet to provide heat to the circulating fluidized bed evaporator for evaporating the wastewater. An outlet is axially above the wastewater inlet and the heat inlet.

Abstract: A distributor for a circulating dry scrubber reactor includes a venturi section with a venturi section wall extending from a venturi section inlet to a venturi section outlet along a longitudinal axis, with the venturi section inlet connected to an inlet plenum and the venturi section outlet connected to a circulating dry scrubber reactor. A hub is mounted within the venturi section wall with an annular converging-diverging flow path defined between the venturi section wall and the hub for distribution of gas flow from the venturi section outlet into a circulating dry scrubber reactor space and for maintaining stable bed fluidization in a CDS system at a comparatively low system pressure loss.

Abstract: Circulating dry scrubbing (CDS) systems and methods utilizes a particle classification unit operation to separate unreacted sorbent (such as lime, limestone, or sodium-based sorbent) such that a reactive fraction of the cut stream may be selectively recovered to a flue gas scrubbing system. This reduces the amount of fresh sorbent that must be supplied for pollutant removal.
