The EPA documents also state that cement kilns burning hazardous wastes do not consistently control HCL and chlorine gas emissions. Indeed the EPAs Toxic Release Inventory shows that the Chanute facility was emitting about a 100 tons per year of HCL from 2004 to 2007 which is within the 2003 to 2008 period where KDHEs screening study .

During the production of cement emissions of SO 2 are generated from the combustion and volatilization of sulfur compounds in the raw material and fuel. The SO 2 in the preheater reacts with CaCO 3 and returns to the kiln as CaSO 4. In the burning zone some of the CaSO 4 is decomposed and will increase the SO 2 circulation in the kiln gas .

Hello Ammar There are really only two practical ways to eliminate a detached plume;- either eliminate the source of ammonia chloride or SO2 in the raw materials particularly organic matter and sulphides such as pyrites or eliminate the acidic components which form ammonium salts in the kiln gases before they leave the stack.
