Cement Kiln Dust for SO2 removal

From 10 to 12 million tons of cement kiln dust accumulates annually at domestic cement plants. This finely divided dust is emitted from cement kilns to prevent the buildup of excessive salts in the cement product. If separated into its valuable components, waste cement kiln dust could become a significant source of potassium and a raw material for making cement. This article does not include the use of this dust for SO2 removal from coal-fired boilers, but potassium is very reactive and would be a good reagent. One question is its use in direct sorbent injection or DSI. There is widespread use of drinking water plant lime sludge as an FGD reagent. So other alternatives should also be explored. The use would be primarily where a small boiler is near a source or where multiple sources can be included so that enough reagent for a large application is available.
