Abstract

Ternary 2–Amino–2–methyl–1–propanol (AMP), Piperazine (PZ) and Monoethanolamine (MEA) amines blended solvent showed its effectiveness as an alternative liquid absorbent in terms of absorption capacity and regeneration heat duty. However, its mass transfer data have not yet been investigated. In the present study, the mass transfer performance of CO2 absorption into AMP–PZ–MEA ternary amines solutions was evaluated in laboratory scale absorption column packed with Sulzer DX structural packing. The absorption performance was presented in terms of overall mass transfer coefficient (KGav) and CO2 removal efficiency. The effects of operating parameters (i.e., liquid flow rate, gas flow rate, and lean CO2 loading) were investigated. The results showed that liquid flow rate and CO2 loading had a significant impact on KGav, while gas flow rate slightly affected KGav. It was also found that KGav increased as liquid flow rate increased but decreased as CO2 loading increased. Additionally, CO2 removal efficiency increased as liquid flow rate increased but decreased as gas flow rate and CO2 loading decreased.
