Claim Text:
1. A system for capturing carbon dioxide from dilute sources, said system comprising: a sorbent wetting and primary unloading unit including a first amount of a secondary sorbent, a supply of water, an inlet for receiving a wet flue gas stream that includes a first amount of carbon dioxide, an inlet for receiving a second amount of said secondary sorbent, an inlet for receiving water from said supply of water, an outlet for transferring said secondary sorbent after it is wetted with water from said supply of water, and an outlet for releasing said wet flue gas stream containing a second amount of carbon dioxide that includes said first amount of carbon dioxide and carbon dioxide unloaded from said secondary sorbent; a conventional primary sorbent unit in fluid communication with said sorbent wetting and primary unloading unit, said conventional primary sorbent unit including a primary sorbent for removing a substantial portion of said second amount of carbon dioxide from said wet flue gas stream that is received from said sorbent wetting and primary unloading unit; drying units in fluid communication with said conventional primary sorbent unit for substantially drying said wet flue gas stream; a secondary sorbent unit in fluid communication with said drying units, said secondary sorbent unit including said second amount of said secondary sorbent for removing substantially all of a remaining portion of carbon dioxide in said wet flue gas stream received from said drying units; and a conduit for transferring said second amount of said secondary sorbent loaded with carbon dioxide from said secondary sorbent unit to said sorbent wetting and primary unloading unit.
