  • Simultaneous reduction of SO2 and NOx in an entrained-flow reactor

    • Simultaneous SO2 and NOx reduction in flue gas by the dry furnace sorbent injection process was simulated with an entrained-flow reactor. Several ammonium salts as well as urea were tested. Urea was found to give the highest NOx removal efficiency. By using urea-limestone sorbent, >90% SO2 removal and >80% NOx removal were obtained at Ca/S and N/NOx ratios both equal to 2. The DeNO(x) process is more temperature-sensitive than the DeSO(2) process, and 900 degrees C can be chosen as the overall optimum temperature. The N2O formed was <10 ppmv at 2 s residence time. A reductive path from NO2 or NO to N-2 is proposed to explain the experimental results.

  • High temperature desulfurization using fine sorbent particles under boiler injection conditions
  • 1995
  • In: Fuel. - 1873-7153. ; 74:5, s. 743-750
  • Journal article (peer-reviewed)abstract
    • The high temperature reaction of SO2 with CaO was investigated in three reactors: a thermogravimetric reactor (TGA), a volumetric reactor (VR) and an entrained flow reactor (EFR). Several natural limestones with super fine particles were used as sorbents. It was found that the reaction could be well characterized by a two-stage process. The initial stage was very fast and lasted about 0.1-0.4 s. The chemical kinetics of the reaction was studied and modelled. In addition to other parameters, such as particle size and Brunauer-Emmett-Teller (BET) surface area, the pore volume located in the larger pores (> 5.0 nm) was found to contribute somewhat to the high SO2 removal and CaO conversion. At Ca/S = 2 the SO2 removal was more than 90%.
