PROCESSES, APPARATUS, COMPOSITIONS AND SYSTEMS FOR REDUCING EMISSIONS OF HCI AND/OR SULFUR OXIDES

摘要

The description relates to reducing emissions of HCI and sulfur oxides by treating combustion gases with an aqueous copper compound referred to as copper-based chloride remediator (CBCR). The process is preferably implemented by identifying locations within a combustor for feeding the CBCR, determining the physical form and injection parameters for the CBCR and injecting the CBCR under conditions effective to reduce HCI and/or sulfur oxides. Effective temperatures for introducing the copper-based chloride remediators are preferably within the range of from about 250° to 900°F where the objective is to reduce HCI, while temperatures up to about 2200°F can be employed where the objective is to reduce sulfur oxides.
