Techniques developed for carbon capture are:
- By absorption and desorption column by alkanolamine based solutions.
- Flue gas scrubbing by MEA (monoethanolamine)
- Membrane separation
- Cryogenic fractionation
- Absorption by molecular sieves
- Adsorption on a solid surface
- Clathrate Hydrates
Carbon storage also considers carbon dioxide capture from the atmosphere and from the flue gases produced at industries by means of chemical absorption and other unit operation techniques. Membrane separation techniques are being recognized as new technology and unit operation which performer completely unique task. They promise effective separation of compounds and utilize energy with minimal loss. These techniques are being studies and develop for more applications.
