Summary

New materials and nanotechnology are becoming an interesting new way to enhance different processes in heat and mass transfer. The addition of nanoparticles in liquid solvents exhibits an enhancement in the gas absorption process. In this study, Al2O3 nanoparticles are combined with methanol to produce nanofluids with the purpose of enhancing the absorption of CO2 gas. The absorption experiments are performed in a tray column absorber. The system is equipped with a mass flow controller, a mass flow meter and a silica-gel unit to remove water vapor from the outlet gas. The parametric analysis on the effect of the particle fraction on the CO2 absorption rate is carried out. The particle fraction ranges from 0.005 to 0.1 vol% of Al2O3 nanoparticles. The maximum CO2 absorption enhancement compared to the pure methanol is obtained ~9.4% at 0.05 vol% of the Al2O3 particles.
