Abstract

Absorption of carbon dioxide from flue gas was investigated in a hollow fiber membrane contactor using methyldiethanolamine + potassium glycinate (MDEA+PG) aqueous solutions. The experimental results showed that the CO₂ removal efficiency increased with the membrane contactor length increasing. CO₂ removal efficiency and the mass transfer rate of CO₂ increased with the increase of liquid flow rate. CO₂ removal efficiency decreased with gas flow rate increasing. CO₂ removal efficiency decreased and mass transfer rate increased with the CO₂ volume fraction inlet increasing. Comparing PG with monoethanolamin (MEA) as auxiliary absorbent, the hybrid solution of MDEA+PG was better than that of MDEA+MEA.
