Research of the Activation of Methyldiethanolamine Absorbing Carbon Dioxide by Monoethanolamine

Abstract:

The absorption of carbon dioxide into aqueous blends of MEA and MDEA is studied in a stirred-cell reactor. The absorption characteristics of MEA and MDEA are compared and the impact of different ratios of MEA to MDEA, MEA and MDEA concentrations on absorption rates and absorption efficiency are researched. The results indicate that small addition of MEA into MDEA could increase greatly absorption rates and efficiency and strengthen mass transfer; and under the condition of fixed MEA concentration, the larger the MDEA concentration, the better the activation effect.
