Title: Method and system to reclaim functional sites on a sorbent contaminated by heat stable salts

Abstract

The objective of this invention is to develop a method to reclaim functional sites on a CO.sub.2 sorbent that have reacted with an acid gas (other than CO.sub.2) to form heat stable salts (HSS). HSS are a significant concern for dry sorbent based CO.sub.2 capture because over time the buildup of HSS will reduce the overall functionality of the CO.sub.2 sorbent. A chemical treatment can remove the non-CO.sub.2 acid gas and reclaim functional sites that can then be used for further CO.sub.2 adsorption.
