Abstract
Air quality control system scrubs flue gas of SO.sub.2 and particulates with a slurry of lime/limestone and water. The contact between the slurry is in a centrifugal section which is the upper part of a tank in which the chemical action is completed and from which the slurry is recirculated to the contact section. The gas to be scrubbed is inserted into a circular path within the scrubbing section into which the slurry is sprayed. The treated gas is withdrawn from the circular path in heat exchange relationship with the incoming gas.
