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.
