Nanoparticles addition is novel technique for enhancement of mass transfer in absorption process. A bubble column was used for investigation of carbon ans sulfur dioxide (CO2 and SO-2) absorption process. Al2O3, SiO2 and Fe2O3 as three different nanoparticles, were used for nanofluid preparation. Results show that Al2O3 is the worst absorbent for CO2 and SO2 absorption in the comparing with the others. Whereas for CO2 absorption, the Fe2O3 is the best absorbent and for SO2 case the SiO2 is the best absorbent. This is occurred due to the difference of polarity in gas molecules. Also the mass transfer rate descended by increasing of gas-liquid contact time due to the reduction of mass transfer driving force. The experimental data were fitted by the exponential correlation and overall liquid-phase mass transfer coefficient (kLa) was separatly calculated for all nanofluids in both CO2 and SO2 cases. Results show that mass transfer coefficient in all cases is 0.003 s-1 because the nanoparticles have the same size.
