The Effect of using Nanofluids as a Solvent in the CO2 Absorption

Mass transfer coefficients are important in the design of mass transfer apparatuses such as distillation towers, absorption towers and cooling towers. The increasing of mass transfer coefficient increases efficiency and reduces size and the cost of equipment. In the present work, the influence of nanoparticles of Al2O3 in base fluid water (nanofluid) for absorption of CO2 in a packed column is investigated. The effect of concentration of nanoparticles on the absorption rate is investigated as important parameters. The results indicated that the optimum value is equal to 0.05 vol%, and also addition of nanoparticles increase the mass transfer rate. Besides, the maximum enhancement of mass transfer rate for nanoparticles of Al2O3 compared to the pure water is 14%.
