| Abstract: | Many methods for gas desulfurization and advantages of the tannin extract method and their principle were introduced.The causes of blockage of the tannin extract desulfurization tower were analyzed.The measures for preventing the problem were discussed.When the sulfur capacity is 1mg/L~200mg/L,the mass concentration of tannin and vanadate should be controlled to 3g/L~5g/L and 2g/L~3g/L,respectively,pH value ≤9 and spraying density ≥20m3/m2·h. |
