Technical and economic analysis of combined treatment of FCC tail gas by ozone denitrification and ammonia desulfurization
GAO Jinhao;GAO Yuan;Changzhou University;Nanjing Ruilin Environmental Protection Co.,Ltd.;
The combined process of ozone denitrification ammonia desulfurization( O_3+NH_3) for FCC( FCC) flue gas treatment is introduced.The technology is that the flue gas first acts under ozone.The NOxin the flue gas is oxidized to high valence nitrogen oxides which are easily soluble in water.Then it enters into the flue gas washing tower and reacts with ammonia to form ammonium sulfite and ammonium nitrate,and ammonium sulfite is oxidized by air to form ammonium sulfate.Compared with the Lo TOx+EDV technology,the total investment of ozone denitrification ammonia desulfurization technology is reduced by about 69%,and the operating cost is reduced by about 39%.
