CA 2469321

A process and apparatus for removing SO2, NO, and NO2 from a gas stream having the steps of oxidizing (60) a portion of the NO in the flue gas stream to NO2, scrubbing (62) the SO2, NO, NO2 with an ammonia scrubbing solution, and removing (64) any ammonia aerosols generated by the scrubbing in a wet electrostatic precipitator. The process can also remove Hg by oxidizing it to HgO and removing it in the wet electrostatic precipitator. Ammonium sulphate, a valuable fertilizer, can be withdrawn from the scrubbing solution.

L'invention concerne un procédé et un appareil, qui permettent d'éliminer le SO<2#191, le NO et le NO?2#191 d'un débit gazeux. Le procédé consiste à: oxyder (60) en NO?2#191 une partie du NO présent dans le débit de gaz d'échappement; épurer (62) le SO?2#191, le NO et le NO?2#191 avec une solution de lavage à l'ammoniac; et éliminer (64) tout aérosol d'ammoniac généré par l'épuration dans un électrofiltre humide. Le procédé permet également d'éliminer Hg par oxydation et transformation en HgO, et par son retrait de l'électrofiltre humide. Du sulfate d'ammonium, un engrais précieux, peut être tiré de la solution de lavage.
