CO2 absorption experiments are performed with two different devices: a tray column and an annular contactor that rotates at different speeds. Al2O3 nanoparticles are suspended in methanol to produce nanofluids with the purpose of enhancing the absorption rate of the CO2 gas into the absorbent. The experimental system has a mass flow controller at the inlet and a mass flow meter at the outlet to measure the absorption rate in the continuous system.
