Abstract
A recovery apparatus of carbon dioxide includes: an absorption column contacting a carbon dioxide-containing gas into contact with an absorbing liquid and allowing the absorbing liquid to absorb carbon dioxide; a regeneration column for regenerating the absorbing liquid to release carbon dioxide; a circulation system which circulates the absorbing liquid to flow from the absorption column and return to the absorption column through the regeneration column; and a steam supply system which generates steam available for a heat source that regenerates the absorbing liquid, using the absorbing liquid that returns to the absorption column and/or the absorbing liquid in the absorption column, and supplies the steam to the regeneration column. High temperature steam is generated from the absorbing liquid and is provided to the regeneration column to use as a heat source for regenerating the absorbing liquid.
