Abstract:
1. A method of removing pollutants from a gas in a fluid scrubber having a weir disposed within a reaction vessel to define first and second volumes within the reaction vessel and a gas delivery tube extending into the reaction vessel into the first volume, the method comprising: supplying scrubbing fluid to the reaction vessel at a rate sufficient to maintain a scrubbing fluid surface level in the reaction vessel above a first end of the weir and at or above a second end of the weir when the pollutants are being removed; providing polluted gas through the gas delivery tube to force the polluted gas through an exit in the gas delivery tube to cause mixing of the polluted gas and the scrubbing fluid within the first volume by creating a circular flow of scrubbing fluid from the first volume upward around the second end of the weir into the second volume and from the second volume downward around a first end of the weir and into the first volume; separating treated gas from the scrubbing liquid as the treated gas and scrubbing liquid pass over the second end of the weir from the first volume to the second volume, and removing the treated gas through an exhaust stack in the reaction vessel, wherein the mixture of polluted gas and scrubbing fluid undergoes chemical reactions that bind the pollutants in the scrubbing fluid.
