SOx and NOx simultaneous removal process for coal power plant flue gas has been developed in pilot plant scale to provide an isothermal, low operating cost method for carrying out the simultaneous removed by liquid phase catalyst for introduce CO2 into the green house for the purpose of CO2 rich horticulture cultivation. Gas purification and carbon dioxide recovery carried out through the muti panel auto circulation bubble lift column reactor utilizing Fe-EDTA as a homogeneous catalyst and conducted for evaluate optimum conditions for flue gas of coal power plant. A novel oxidation-removal process capable of removing NOx and SOx simultaneously was proposed, which utilized the injection of ·OH radicals from H2O2 catalytic decomposition with iron ions. The stack gas composition were 15% CO2, 9ppm CO, 34ppm NO , and 34ppm NOx , respectively. After passed the reactor, flue gas were 15% CO2, 7ppm CO, 19ppm NO and 19ppm NOx , respectively. SO2 was completely removed to trace concentration and NOx was reduced to 19ppm(56% removal efficiency). In case of CO, removal is too low, because of its low solubility in liquid phase reaction. we introduced metal loaded active carbon as CO and remain NO removal. |
