The SO{sub 2} removal efficiency was studied for concentration in the range of 333--3000 ppM (parts per million). Since the sulfur content of Illinois coal is high, the SO{sub 2} concentration in typical flue gas is in the high end of the range shown above. With high concentration of SO{sub 2} the removal efficiency decreases. However, the removal scales well with applied voltage, electrode length, and supply frequency. In this period the modeling of the process was also accomplished. The results show that a Townsend-type discharge is more efficient than a streamer type discharge in producing OH and 0 radicals. This explains why UV-irradiation helps the removal efficiency. The details are discussed in the report.
