For ammonia flue gas desulfur那器ization (FGD), the sulf用對ite to sulfate oxidation is very criti秒船cal for industrial application現相s. This paper reports a novel corona pl飛體asma-induced oxidation t路制echnique to convert concentrate身件d ammonium sulfites to sulfates in an 兒業aqueous solution. The streamer去開 corona plasmas are generate中在d with a dc superimposed ac powe訊工r source. Ammonium sulfi自用te solution is sprayed in a 秒對reactor by using two草議-phase nozzles. When the sulfite conc外可entration is around 1–3 mol/L , the oxidation effi讀吧ciency after one-cyc話銀le processing is in t長歌he range of 20–60%. Multiple-cy見跳cle treatments can be used to imp火鄉rove the oxidation efficiency.呢懂 The energy consumption is around 20 著區W/ mol . Based on the present investig謝服ations, we anticipat小麗e that an industrial plasma-嗎志assisted ammonium FGD can be ap美很plied in industries.
