Summary

In this study, SiO2 nanoparticles and methanol are combined into SiO2/methanol nanofluid to enhance the CO2 absorption rate of the base fluid which is pure methanol. The absorption experiments are performed in the bubble type absorber system equipped with mass flow controller (MFC), mass flow meter (MFM) and silica-gel (which can remove water vapor in the outlet gases). The parametric analysis on the effect of the particle fraction on CO2 absorption rate is carried out. The particle fraction has ranges from 0.005 to 0.5 vol% for the SiO2 particles. The maximum CO2 absorption enhancement compared to the pure methanol were obtained ~2.8 % at 0.05 vol% particles in 20°C, and ~5.6 % at 0.01 vol% particles in -20°C, respectively. In addition, experiment was carried out to study the characteristics of nanoparticle size of SiO2/methanol absorbent. The SiO2/methanol absorbent is expected to be a promising material to enhance the CO2 absorption performance.
