Separation of CO2 by 2-Amino-2-Methyl-1-Propanol Aqueous Solution in Microporous Hydrophobic Hollow Fiber Contained Liquid Membrane
The absorption of CO2 from a mixture of CO2/N2 gas was carried out using a flat-stirred vessel and the polytetrafluoroethylene hollow fiber contained aqueous 2-amino-2-methyl-1-propanol (AMP) solution. The reaction of CO2 with AMP was confirmed to be a second order reversible reaction with fast-reaction region. The mass transfer resistance in the membrane side obtained from the comparison of the measured absorption rates of CO2 in a hollow fiber contained liquid membrane with a flat-stirred vessel corresponded to about 90% of overall-mass-transfer resistance. The mass transfer coefficient of hollow fiber phase could be evaluated, which was independent of CO2 loading.
