Acidic gases like CO2, SO2, NO2, H2S, etc., are to be removed as these are polluting the atmosphere in one way or another by inducing temperature rise which further results in undesirable climatic change. Among all these gases, CO2 is the most responsible for the environmental issues and its capture becomes one of prime importance. The objective of this work is the enhancement of the CO2 absorption by employing nanofluids in the presence of magnetic field. The nanofluid used in this work is Al2O3/water in the concentration of 0.0015%. The maximum flux obtained is 0.014 mol/(m2s) (without magnetic field) and 0.015 mol/(m2s) (with magnetic field) for lower CO2 flow rate of 30 L/h. The nanofluids along with the magnetic field show a positive performance towards the absorption of CO2.
