Experimental Study on Separation of CO2 by Using Hollow Fiber Membrane Contactors with Amino Acid Salts Solutions

Abstract:

Article Preview

Experimental on CO2 removal from flue gas using polypropylene hollow fiber membrane contactors were conducted in this study. Absorbents including aqueous PG, SG were used to absorb CO2 in the experiments, and comparing with aqueous MEA. The experimental results showed that the mass transfer rate of PG and SG increased gradually in experiments while the absorbent concentration can not be elevated without limitation. That may show the mass transfer rate will be eventually saturated at a certain concentration value. The aqueous PG can be selected to absorb CO2 in membrane contactors at a lower liquid flow rate to reduce the potential to wet the membrane. Comparing PG and SG with MEA. The performance of PG is superior to SG and MEA under the same operating conditions.
