Progress in carbon dioxide capture from flue gas by pressure swing adsorption

The disposition of excessive carbon dioxide from industries, namely carbon dioxide capture and storage (CCS), is summarized. Four types of carbon dioxide separation techniques as well as an industrial carbon dioxide capture system are introduced. The principle of pressure swing adsorption (PSA) and its application in carbon dioxide capture from flue gas are described. Recent developments in PSA cycle design, adsorbents, simulations and industrial applications are reviewed. Existing problems that need to be resolved in current PSA technologies are analysed. It is concluded that PSA is a promising technology for carbon dioxide capture.
