icroporous membrane absorbers were used for separation of carbon dioxide andnitrogen. The membrane was made of polytetrafluoroethylene (PTFE) and the absorbentswere distilled water and alkanolamines such as monoethanolamine (MEA) and2-amino-2-methyl-1-propanol (AMP). In this paper, we determined the separationefficiency and the overall mass transfer coefficient of carbon dioxide in the membranemodule. The separation performance of the membrane absorber was evaluated in termsof the absorbent concentration and temperature. The absorption rates through the PTFEhollow fiber membrane were measured at three different temperatures ranging from 20(Cto 60(C. The removal rate of carbon dioxide was increased with the volume flow rate ofan absorbent and reached saturation at a certain value. Good agreement was foundbetween the experimental measurements and the model predictions for the aqueousamine solutions.
