| Abstract: | Mass transfer of NOx in the liquid phase was analysed.Using three different absorbents made of urea and ammonium,wet denitrification was investigated in sprinkling absorption reactors filled with steel pall rings.A series of experiments were carried out to study operation parameters,such as gas velocity,ratio of liquid to gas,absorbent concentration,gas temperature,absorbent temperature,additive concentration,NOx concentration and SO2 existence.The experimental results indicated that urea solution was more ... |
