Method Using Lime Slurry For Regenerating Sodium Sulfite In Double Alkali Flue Gas Desulfurization Process
US Patent:
4267156, May 12, 1981
Filed:
Jul 11, 1979
Appl. No.:
6/056467
Inventors:
Leonard Dauerman - Ft. Lee NJ

International Classification:
C01B 1700
US Classification:
423242
Abstract:
In the process of desulfurizing flue gases in which an alkaline solution of sodium, such as sodium sulfite or sodium hydroxide, is contacted with gases in a scrubber to produce a sodium bisulfite solution, an improved method is provided for substantially reducing the time and equipment required to regenerate the sodium solution. In the method, a lime slurry stream and a sodium bisulfite stream are conflowed into a bifurcated mixing nozzle having a pair of converging inlets and a common outlet. The confluence of the streams in the nozzle creates turbulence which causes the lime slurry to react substantially instantaneously with the sodium bisulfite solution to regenerate the sodium solution which is recycled to the scrubber and a calcium sulfite precipitate which is filtered from the sodium solution and discarded.

International Classification:

US Classification:
423242
Abstract:
In the Double Alkali flue gas desulfurization process wherein sodium bisulfite is produced in a scrubber from the reaction of sulfur dioxide laden flue gases with an aqueous solution of sodium sulfite, the sodium sulfite is regenerated from the sodium bisulfite by reacting the same with a limestone slurry in a bifurcated mixing nozzle having a pair of converging inlets communicating with a common outlet. The reactants are flowed into the inlets at flow rates sufficient to produce turbulence in their zone of confluence in the nozzle to initiate a reaction which, although incomplete in the nozzle, proceeds at a rapid rate to completion after the mixed reactants leave the nozzle.
