Abstract :
SO/sub 2/ and NO/sub x/ removal by streamer corona discharges is proposed, and the role played by H/sub 2/O and NH/sub 3/ in the system is discussed. The results show that: (1) the ion-molecule reactions play an important role in the SO/sub 2/ and NO/sub x/ processes as well as the radicals reactions; (2) the effects of gas temperature and electron energy cannot be neglected in current processes; and (3) the effect of H/sub 2/O and NH/sub 3/ concentrations and external electric field becomes a significant influence on the current processes owing to the importance of the ion/molecule reactions and volume recombinations.<>
