Kinetic study on promoted potassium carbonate solutions for CO2 capture from flue gas

A review: Desorption of CO 2 from rich solutions in chemical absorption processes

“…However, the challenge of using potassium carbonate is that slow reaction kinetics and low mass transfer rates need to be improved (Astarita et al, 1981;Ghosh et al, 2009). The interest in using potassium carbonate as absorbent was renewed because of the enhancement of reaction kinetics by employing additives (Behr et al, 2011(Behr et al, , 2013. And a big advantage of carbonate solutions is that compared with amines, it has a relatively low heat of absorption, which means that the desorption of carbonates has a lower energy requirement.…”

CO2 capture with potassium carbonate solutions: A state-of-the-art review

“…Addition of boric acid increased the CO 2 absorption rates, but it is still not comparable to the absorption rates in the amine solutions. Behr et al (2011) applied a bubble reactor and a WWC to investigate the kinetics of promoted PC solutions in capturing CO 2 . They employed PZ, MEA, MDEA, and some organic polymers as promoters.…”
