A gas-liquid contactor is provided for removing gases and particulate matter from flue gases, such as those which are produced by processing operations of the type carried out in utility and industrial facilities. The gas-liquid contactor includes a tower into which a slurry is introduced for absorbing gases and particulate matter, and is configured so as to eliminate the requirement for a pump to deliver the slurry to the tower. In addition, the tower is configured to accommodate a maximum flue gas flow velocity through the tower while maintaining proper operation of the tower. Liquid particles in which the gases and particulate matter are entrained are collected in a tank, through which the slurry is recycled to the tower. The level of the slurry within the tank is higher than the entry point of the slurry into the tower, such that the slurry returns to the tower under the force of gravity.

Flue gas scrubbing apparatus

A method for scrubbing flue gases utilizing a spray tower for removing acidic gases and particulate matter from flue gases produced by processing operations of the type carried out in utility and industrial facilities. The spray tower is equipped with a tank 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 located within the tower. The spray tower further includes an internal structure 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.

A spray tower is provided for removing gases and particulate matter from flue gases which are produced by processing operations of the type carried out in utility and industrial facilities. The spray tower is configured so as to minimize its overall height, such that construction, operational and maintenance costs of the tower are also minimized. A tank located at the base of the tower serves as a reservoir for an alkaline slurry used to remove gases and particulate matter from the flue gases. The slurry is pumped from the tank to spraying devices located within the tower. An inlet is located above the tank through which the flue gases are introduced into the tower. Disposed within the tower and adjacent the inlet is an enclosure having an upper end joined to the tower and a lower end defining an opening. Spraying devices are located within the enclosure, preferably at approximately the same height as the inlet, so as to enable the overall height of the tower to be reduced.
