Abstract
Two or more liquid reagents are caused to react simultaneously within the same reaction vessel with different components of a gas stream. The gas stream being treated is introduced into the top of a reaction vessel and is withdrawn from the bottom. A first chemical reagent is introduced into the top of the vessel in the form of a finely divided spray. The second liquid reagent is introduced in like fashion at a lower level. The two sprays are allowed to travel unimpeded to the bottom of the tower while reacting with different components of the gas stream.
