This Small Business Innovation Research (SBIR/STTR) project focused on the development of mitigation strategies to decrease the quantity of aerosols that are formed from amine-based reactive absorption post-combustion capture systems in the presence of alkali, sulfur trioxide and other compounds. The key to this novel approach is to understand the source of these aerosols and to prevent/modify their formation. During this Phase I project, sorbent injection to prevent formation of alkali-type aerosols was investigated using a down-fired combustor. The key area of interest was the aerosol loading in the sub-micron range, demonstrated to cover the problematic range for CO2 capture systems. A low cost sorbent showed effective reduction of the sodium and particulate loading in the target sub-micron size by ~75% and 64% respectively. This report summarizes the work completed during this Phase I project, consisting of proof-of-concept testing to modify the formation of alkali-based aerosols so as to facilitate their removal from coal combustion flue gas streams prior to a wet CO2 capture system.
