Inventors:

Holly Krutka - Centennial CO, US

William J. Morris - Evergreen CO, US

International Classification:

B01D 53/96

US Classification:

423228, 422168, 422105, 423210, 4232427

Abstract:

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

International Classification:

US Classification:

423210, 4234371, 422142

Abstract:

The present disclosure is directed to a process that allows dry sorbents to remove a target constituent, such as carbon dioxide (CO), from a gas stream. A staged fluidized bed separator enables gas and sorbent to move in opposite directions. The sorbent is loaded with target constituent in the separator. It is then transferred to a regenerator where the target constituent is stripped. The temperature of the separator and regenerator are controlled. After it is removed from the regenerator, the sorbent is then transferred back to the separator.
