Experiments on the PPCP pilot flue gas desuflurization (FGD) plant with the activated ammonia and vapor were made while adjustments of the pulse generator and integration of the plasma reactor with the byproduct catcher were conducted, and composition of the byproduct was analyzed. With a flue gas flow of 4 500~11 000 m+3-N/h, and temperature about 60～70 ℃ at the entrance of the plasma reactor, and stoichiometric ratio of NH-3 to SO-2 about 1∶1, and stable continuous operation of the facility, and single electric field integrated with the plasma reactor to collect the byproduct, the results can be achieved that byproduct collection efficiency 20%~30% by the activated ammonia and vapor electric field, and over 85% by the catcher with one electric field, and ratio of the SO 2- 4∶SO 2- 3 in the byproduct over 95∶5, and SO-2 removal over 90 percent.
