It is easy to dismiss the pre-formed spray type scrubber as simply a cyclonic separator outfitted with spray nozzles. It is more complicated than that.
This type scrubber has two-design situations that need to coexist. Small droplets are needed to achieve the desired particulate removal and gas absorption while larger droplets are needed to provide adequate liquid separation from the gas stream.
