Carbon dioxide (CO 2 ) is one of the main factors for climate change issues. Absorption is the technology to remove CO 2 from various industries. The equipment used is the packed column to promote high mass transfer rate and to study the overall mass transfer coefficient (K G a v ). The K G a v is an important parameter for designing and scaling up of packed column. Therefore, the objective of this work is to measure K G a v for CO 2 absorption into the aqueous solution of monoethanolamine (MEA) in a random-packed column and to investigate effect of parameters on K G a v . The parameters are the solvent flow rate from 5.3-15.9 m 3 /m 2 h, CO 2 initial loading from 0.0-0.2 mole/mole and CO 2 content in gas phase from 5-15 %v/v. The results show that K G a v increases as the solvent flow rate and solvent concentration increase. The CO 2 content in gas phase provides relatively high impact on K G a v with an increase in the CO 2 content.
