خلاصه مقاله:
In this study a new method for enhancing the mass transfer coefficient in the gas absorption process is reported. Absorption of CO2 was measured into an aqueous solution of Al2O3/Water nanofluid in a wetted wall column. γ -Alomina nanofluid with the concentrations of 0, 0.01,0.05, 0.1, 0.5, and 1 v/v % has been used as solvent. Effects of some parameters such as gas and liquid mass flow rate and nanoparticle concentration on mass transfer coefiicient has beeninvistigated expaerimentally. It is found that the mass transfer enhancement from the Al2O3/Waternanofluid becomes higher than that from the base fluid (water). The value of volumetric liquidside mass transfer coefficient (kL), increased with increasing Alumina nanoparticles concentration. The maximum enhancement of mass transfer belongs to the 1% volume fraction ofaluminium oxide which increase the mass transfer coefficient up to 55%.
