Abstract
The operation of wet scrubbers, especially those based on calcium carbonate, is improved by reducing the quantities of soluble chlorides in the combustion gases fed to the scrubbers. HCl in the combustion gases is converted to a solid copper chloride and removed before the chloride reaches the scrubber. Combustion gases are treated with an aqueous copper compound referred to as copper-bearing chloride remediator (CBCR). Effective temperatures for introducing the CBCRs are preferably within the range of from about 250° to 900° F. Among the more preferred CBCRs are copper compositions including copper, an organic moiety and/or an ammonia moiety.
