Description
This Gas Absorption Unit is designed to
provide students with a hands-on experience
on gas absorption by means of liquids
(solvent absorption).
This unit consists of:
• Absorption packed column
• Sump tank
• Feed pump
• Instrumentations for measurement of air, liquid and
gas flow rates and column pressure drop
Experimental capabilities:
• Absorption of CO2 from air-CO2 mixtures using
sodium hydroxide solution
• Determination of CO2 saturation point in NaOH
solution and time to reach saturation
• Effect of CO2 compositions, air and liquid flow rates
on absorption efficiency
• Hydrodynamics of a packed column
• Determination of loading and flooding points of the
column
