Fossil fuel burning and industrial gaseous emissions are releasing CO2into the atmosphere which is responsible for at least 55 % of global warming today. Pakistan is one of the most severely hit countries by global climate change and the consequences are evident from the fast receding glaciers, floods, droughts and heat waves. Carbon sequestration technology consists of various methods employed to remove CO2 from the atmosphere. This paper presents the prototype design of amine-based CO2 capture technology. It uses two amine solvents: Monoethanolamine (MEA) and diethanolamine(DEA) in varying concentrations to test the efficiency of the system (solvent and scrubber). It was discovered that MEA solution at 30% concentration yielded the highest efficiency. The scrubbing reaction is exothermic. Corrosion of the scrubber vessel was identified as a problem in applying this method of sequestration.
