Abstract
Ethanolamine solutions are a kind of important absorbent for carbon dioxide capture from flue gas. In this work, the absorption rate and absorption capacity of carbon dioxide by ethanolamine and piperazine solutions have been studied. Using a newly absorption equipment, the absorption rate was measured in monoethanolamine, diethanolamine and piperazine solutions with different concentration from 10 to 50 wt %, respectively. The experimental results showed that monoethanolamine and diethanolamine both have a large absorption rate and capacity. According to the experimental results and the zwitterion mechanism, the kinetics of the reaction between carbon dioxide and ethanolamine could be derived.
