Claim Text:
1. An apparatus for integrating a carbon dioxide capture function and a desalination function, the apparatus comprising: an absorption unit absorbing carbon dioxide included in a flue gas by bringing the flue gas into contact with an absorption solution in which a volatile absorbent absorbing carbon dioxide is dissolved; a draw solution chamber storing the absorption solution that flows in from the absorption unit, the draw solution chamber using the absorption solution as a draw solution; a forward osmosis separator separating fresh water from raw water by a forward osmosis method using the draw solution flowing in from the draw solution chamber; a buffer chamber fluidly connected to the draw solution chamber, the draw solution passing through the forward osmosis separator to become a diluted draw solution, and a portion of the diluted draw solution flowing into the buffer chamber; a fresh water separating unit separating fresh water from the diluted draw solution that has passed through the forward osmosis separator; a carbon dioxide separating unit separating carbon dioxide from the draw solution supplied from the buffer chamber, the carbon dioxide separating unit fluidly connected to the absorption unit such that the draw solution, from which the carbon dioxide is separated, flows into the absorption unit so as to be reused as the absorption solution; and a control unit controlling concentrations and amounts of the draw solutions stored in the draw solution chamber and the buffer chamber, wherein a portion of the carbon dioxide separated in the carbon dioxide separating unit flows into the draw solution chamber.
