1. A carbon dioxide removal system comprising:
- a chilled ammonia carbon capture system (CAP);
an absorber refrigeration system in fluid communication with the chilled ammonia carbon capture system;
a heat recovery steam generator (HRSG) in fluid communication with the chilled ammonia carbon capture system and the absorber refrigeration system;
a refrigerant stripper and a reboiler both in fluid communication with the chilled ammonia carbon capture system, the absorber refrigeration system, and the HRSG; and
a CAP stripper condenser in fluid communication with the refrigerant stripper and the absorber refrigeration system.

12. A method for reducing power consumed during a carbon capture process, comprising:
-
in a carbon dioxide removal system comprising; a chilled ammonia carbon capture system; an absorber refrigeration system in fluid communication with the chilled ammonia carbon capture system (CAP); and a heat recovery steam generator (HRSG) in fluid communication with the chilled ammonia carbon capture system and the absorber refrigeration system; contacting the chilled ammonia carbon capture system with the absorber refrigeration system without the use of a mechanical refrigeration system; and
further comprising;providing a heated liquid stream comprising ammonia from the absorber refrigeration system to a CAP stripper condenser; and providing the heated liquid stream from the CAP stripper condenser to a refrigerant stripper. - View Dependent Claims (13)
