CO2 Absorption from Its Mixture with CH4 or N2 through Hollow Fiber Membrane Contactor using Water asSolvent. Hollow fiber membrane contactors have been widely used as gas-liquid contactors recently such as in the CO2absorption process from gas stream. This research aims to evaluate the effectiveness of hollow fiber membranecontactor to absorb CO2 from its mixture with CH4 or N2 using water through mass transfer and hydrodynamic tests.There are 3 membrane modules used in this research with shell diameter of 1.9 cm, length of 40 cm, outer fiberdiameter of 2.7 mm and fiber number in the contactors of 10, 15 and 20. Liquid flow rates in the hollow fiber membranecontactors are varied in this research. Research results show that mass transfer coefficients in the membrane contactorincrease with increasing liquid flow rate and decrease with increasing fiber number in the contactor. Flux of CO2 intowater can achieve 1.4x10-9 mol CO2 /m2.s and mass transfer coefficients can achieve 1.23 x 10-7 m/s. Meanwhile,hydrodynamic test results show that water pressure drop in the membrane contactors increase with increasing fibernumber in the contactors.
