Abstract
Sulfur oxides are removed from a flue gas stream with an upflow quench reactor, a dry venturi and a baghouse. The lime slurry used in the quench reactor is doped which enhances the neutralization reaction in the dry venturi and the bag filter. The use of the dry venturi allows a substantial buildup of solids on the filter wherein the baghouse functions as a fixed bed reactor.
