Abstract:
1. A system removing contaminants from a contaminated air stream, the system comprising: a decontamination tank gas scrubber tower; solvent supply lines for providing solvent; a nozzle connected to the solvent supply lines and positioned at the top of the gas scrubber tower, the nozzle operable to downwardly disperse the solvent into the tower; a gaseous stream passage for passing a contaminated gaseous stream through the tower, whereby the contaminated gaseous stream is directed upwardly through the downwardly dispersed solvent, whereby contaminants are transferred from a gaseous phase to an aqueous phase and thereupon travel downward to the bottom of the gas scrubber tower; a slurry positioned to receive the aqueous phase contaminants; and a photocatalytic decontamination system operable to remove the contaminants from the slurry.
