CARBON DIOXIDE RECOVERY SYSTEM

摘要

This carbon dioxide recovery system for separating and recovering carbon dioxide from an input fluid that contains the carbon dioxide is provided with: an absorption tower which produces a rich absorption liquid by having the carbon dioxide contained in the input liquid absorbed therein; a regeneration tower for heating the rich absorption liquid and separating the carbon dioxide therefrom; a circulation circuit which is arranged between the absorption tower and the regeneration tower and through which a compressible fluid is circulated; a first heat exchanger which is arranged in the absorption tower and constitutes a part of the circulation circuit; a second heat exchanger which is arranged in the regeneration tower and constitutes a part of the circulation circuit; a first compressor which is arranged in the circulation circuit and sends the compressible fluid from the absorption tower towards the regeneration tower; and a first expander which is arranged in the circulation circuit and sends the compressible fluid from the regeneration tower towards the absorption tower.
