<p>A spray tower for removing acidic gases and particulate matter from flue gasses produced by processing operations of the type carried out in utility and industrial facilities. The spray tower is equipped with a tank (122) that serves as a reservoir for an alkaline slurry used to remove acidic gases and particulate matter from the flue gases. The slurry is pumped from the tank to spraying devices (118) located within the tower. The spray tower further includes an internal structure (134) that enables the slurry to be oxidized and gently agitated within a limited region of the tank, and without the requirement for two separate aeration and agitation devices. As a result, the construction, operational and maintenance costs of the spray tower are significantly reduced as compared to prior art spray towers.</p> |
