Review on CO2 Capture Using Amine-Functionalized Materials
To improve CO 2 capture technology, two major drawbacks of amine scrubbing need to be overcome: (1) energy-inefficient regeneration at high temperature and (2) waste management of the degraded solvent containing amines. In light of this, CO 2 capture using solid materials has recently come under the spotlight.
Amine gas treating - Wikipedia
Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
Amine-Based CO2 Capture Technology Development from the Beginning …
2015年1月21日 · Notable among CO 2 capture technologies are amine-based technologies. Amines are well-known for their reversible reactions with CO 2, which make them ideal for the separation of CO 2 from many CO 2-containing gases, including flue gas. For this reason, this review will cover amine-based technology developed and published in and after the year 2013.
