Patent attributes
The present invention relates to an apparatus for integrating carbon dioxide capture and desalination. The apparatus includes 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 supplied from the absorption and 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 supplied with a portion of the diluted draw solution that has passed through the forward osmosis separator, 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, and a control unit controlling concentrations and amounts of the draw solutions stored in the draw solution chamber and the buffer chamber.
