Abstract
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.
