| 摘要 |
The present invention relates generally to the field of post-combustion carbon dioxide capture. The method and apparatus involves utilizing an amine-based absorption compound for flue gas, or combustion gas to capture C02, according to embodiments of the present invention. In some embodiments, C02 is delivered from a wet, or dry, flue gas scrubber to an absorber. The amine-based absorption compound is introduced in an aqueous solution to the absorber, which is located downstream of the wet, or dry, flue gas scrubber. In some embodiments, the C02-laden amine-based absorption compound is then subjected to a regeneration step to regenerate the C02-laden amine-based absorption compound and strip out absorbed C02. In some embodiments, energy is supplied to a stripper through a reboiler to accomplish the regeneration step. |
