Experimental Study on Denitrification and Desulphurization of Flue Gas by Alkaline Solvent Combined with Liquid Phase Oxidant
Sulfur dioxide and nitrogen oxides from coal burning are the most important sources of air pollution in China.The development of new flue gas treatment processes is still the focus of international research.This project intends to use KMnO4 as oxidant to absorb desulfurization and denitrification by using composite liquid NaOH,and study its mechanism,so as to lay a theoretical basis and technical support for the promotion and application of multi-pollutant collaborative removal technology in coal-fired flue gas.The results show that the desulfurization and denitration of KMnO4 and NaOH can make the removal rate of SO2 reach about 98%and the removal rate of NOx reach about 60%,which realizes the high removal rate of SO2 and NOx in flue gas.
