Abstract
A power generation plant (), a method, and a COcapture system () for removing carbon dioxide () from a flue gas stream () are disclosed. As shown in FIG., a COcapture system (), comprises an absorber vessel (), a water wash vessel (), and a stripper (). The COcapture system () can be configured to introduce both a lean ionic ammonia solution () from a regeneration system () and a flue gas stream () from a cooling system () and to provide a rich ionic ammonia solution () to a regeneration system (), wherein the introduction of the lean ionic ammonia solution () to the flue gas stream () produces a flue gas substantially devoid CO(). The water wash vessel () can be configured to receive the flue gas substantially devoid CO() and produce ammoniated water () by introducing water () to the flue gas substantially devoid CO(). The stripper () can be configured to receive the ammoniated water () and to remove ammonia () from the ammoniated water () thereby producing a cleaned flue gas stream (), the stripper () being operable in at least partial vacuum conditions.
