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 The gas stream being treated is introduced into the top of a reaction vessel and is withdrawn from the bottom.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.
Claims13
A method for simultaneously reacting multiple components of a gas stream with two or more liquid reagents which comprises:
- passing said gas stream into an upper level of a reaction zone;
- introducing into the upper level of said reaction zone a finely divided spray of a first liquid reagent, the droplet size of said spray having a median diameter of less than about 10 microns;
- introducing a finely divided spray of a second liquid reagent into the same reaction zone at a level below that of said first liquid reagent but substantially above the bottom of said zone, the droplet size of said second reagent spray having a median diameter of less than about 10 microns;
- allowing the droplets of said first and second liquid reagents to travel unimpeded to the bottom of said zone;
- maintaining the gas flow through said reaction zone at a rate which allows a contact time between the spray droplets of said liquid reagents and the gas stream of at least about 5 seconds;
- removing settled out spray droplets containing the reaction products of both said first and second reagents with components of the gas stream from the bottom of the reaction zone, and
- separately removing the gas stream from a lower level of the reaction zone.
