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.
