Abstract
Simultaneous desulfurization and denitrification removes SO2 and NOx from flue gas in one unit and only uses one absorbent. Using urea as absorbent removing SO2 and NOx in semi-dry spouted bed has the enormous developmental potential and wide foreground for it overcomes two shortages of wet process such as the amount of urea is large and the waste water is difficult to handle. The chemical absorption mechanism and thermodynamics of SO2 and NOx with urea were studied, the operating condition optimization of spouted bed was determined through several repeating experiment, the effects of some important operational parameters such as molar ratio of urea and gaseous pollutant, inlet temperature of flue gas and approach to adiabatic saturation temperature on SO2 and NOx removal efficiency were analyzed. The results provide a foundation for the commercial scale application of simultaneous desulfurization and denitrification technology.
