On the desulfurization using complexed iron
Thread Content
When the complexed iron desulfurization process is used, and the ammonia content in the acidic gas is high (20-30%), what impact does this have on the desulfurization efficiency of complexed iron? Will it increase the consumption of desulfurization agents?
It won’t happen. It’s better to first use an ammonia removal device to get rid of the ammonia. Otherwise, the odor at the outlet of the oxidation tower will be quite strong. Ammonia water promotes the absorption of hydrogen sulfide. So it will reduce the alkali consumption of the system
