Abstract
Carbon dioxide (CO2) emissions are the main source of global warming as it causes greenhouse effect. Various techniques are used to control the amount of CO2 among which post combustion capture are used to remove CO2 from the atmosphere. Efficient and cost effective removal of CO2 is carried out by absorbing it in water, which is a cheap solvent and abundantly available. A study on the removal of CO2 in a packed bed column has been carried out to observe the effect of liquid flow rate, gas flow rate and temperature. Absorption of CO2 decreased from .92 to .564 with the increase in liquid flow rate from 2 to 10 L/min. Strength of CO2 increased from 1.452 to 2.01 with the increase in gas flow rate from 2 to 10 L/min. Temperature of the solvent have inverse effect on absorption of CO2 which goes onto decrease from .322 to .121 with rise in temperature from 30 to 50 oC.
