Publication: Journal of Environmental Engineering
Volume 146, Issue 7
Abstract
In this study, a new technology was proposed for removing and NO from industrial flue gas via wet catalytic oxidation technology that uses a mud-phosphorus emulsion as the absorption liquid. In this study, the optimal reaction temperature, gas rate, oxygen content, and mud-phosphorus emulsion solid-to-liquid ratio were determined. At a reaction temperature of 60°C, the gas flow rate was , the oxygen content was 20%, and the solid-to-liquid ratio in the mud-phosphorus emulsion was . When the system was operated for 880 min, the desulfurization rate was 99%; when the system was operated for 860 min, the denitrification rate was still 99%, and the desulfurization and denitrification effects were ideal. The proposed technology opens new avenues for the purification and resource utilization of sulfur-containing flue gas.
