Recently, the new high-efficiency gas-phase desulfurization technology developed by the School of Chemistry and Chemical Engineering of Shandong University has a desulfurization rate of 95%~99%, and the emission concentration of sulfur dioxide (SO2) after desulfurization is less than 50mg/Nm3
.
Compared with the liquid phase flue gas desulfurization technology widely used at present, the new technology has high efficiency, low cost, simple equipment required, small investment, operating cost can be reduced to less than 2 yuan / kg sulfur dioxide, and the desulfurization product can be used as agricultural fertilizer
after collection.
