CO2capture using α-Al2O3nanofluid in a hollow fiber membrane contactor

In this work, performance of α-alumina nanofluid as a solvent for CO2 absorption in a gas-liquidhollow fiber membrane contactor is investigated. Effects of important parameters on gasabsorption such as concentration of nanoparticles, gas flow rate, solvent flow rate and CO2concentration in feed were investigated.The results showed that the CO2 absorption efficiency hasincreased by using α- Al2O3/Waternanofluid By using .compared with water as a solvent inthe 0.02 vol. % α-alumina nanofluid, CO2 removal efficiency in low gas flow rates reached to87%, in low feed CO2 concentration reached to 54% and in high solvent flow rate reached to 51%.
