Abstract

A power generation plant (112), a method, and a CO₂ capture system (122) for removing carbon dioxide (104) from a flue gas stream (106) are disclosed. As shown in FIG. 2, a CO₂ capture system (122), comprises an absorber vessel (202), a water wash vessel (210), and a stripper (214). The CO₂ capture system (122) can be configured to introduce both a lean ionic ammonia solution (204) from a regeneration system (124) and a flue gas stream (106) from a cooling system (120) and to provide a rich ionic ammonia solution (206) to a regeneration system (124), wherein the introduction of the lean ionic ammonia solution (204) to the flue gas stream (106) produces a flue gas substantially devoid CO₂ (224). The water wash vessel (210) can be configured to receive the flue gas substantially devoid CO₂ (224) and produce ammoniated water (212) by introducing water (218) to the flue gas substantially devoid CO₂ (224). The stripper (214) can be configured to receive the ammoniated water (212) and to remove ammonia (216) from the ammoniated water (212) thereby producing a cleaned flue gas stream (116), the stripper (214) being operable in at least partial vacuum conditions.
