Abstract
The invention relates to processes for reducing emissions of hydrochloric acid (HCl) to moderate pollution to the environment and achieve regulatory compliance in a cost-effective manner. In embodiments described below, the invention deals with reducing HCl and does not require a sorbent but utilizes an aqueous composition we term a copper-bearing chloride remediator (CBCR). In one general case, the CBCR can be a member selected from the group consisting of compositions defined by the formula Cu(NH)(carbonate or lower carboxylate), wherein the lower carboxylate is selected from the group consisting of formate, acetate and propionate, x is an integer from 0 to 4, y is an integer from 0 to 2, and x+y is equal to or greater than 1.
