Abstract

In the present study, suspensions of Al ₂O ₃ and SiO ₂ nanoparticles in methanol (nanofluid) are produced and analyzed for the application of CO ₂ absorption in a tray column absorber. The absorber is an acrylic tray column with twelve plates. The column is a sieve tray type which has flat perforated plates where the vapor velocity keeps the liquid from flowing down through the holes and the CO ₂ gas and methanol liquid are brought in contact in a counter-current flow. The test section is equipped with two mass flow meters to measure the absorption rate. The results show maximum enhanced absorption rates of 9.4% and 9.7% for Al ₂O ₃ and SiO ₂ particles (compared to pure methanol), respectively. It is also found that SiO ₂ nanoparticle is a better candidate than Al ₂O ₃ nanoparticle and 0.05 vol% of nanoparticles is an optimum condition for CO ₂ absorption enhancement for the present experimental conditions.
