WET DENITRATING METHOD OR WET DENITRATING AND DESULFURIZING METHOD BY USE OF OZONE

摘要

PURPOSE:To increase reaction ratio of O3 with NO contained in exhaust gas so as to utilize O3 efficiently, by countercurrent contact of the exhaust gas with a gas contg. dil. O3 gas obtd. by dilution of oxidizing agent i.e. ozoinzed air diluted with an oxidation-resistant gas, and by subjecting the exhaust gas to successive wet denitration or wet denitration and desulfurization.
