Experimental Study on Separation of CO_2 from Flue Gas Using Hollow Fiber Membrane Contactors

摘要

This work presents an experimental investigation for removing CO_2 from the flue gas with hollow fiber membrane contactors. The CO_2 was absorbed into aqueous monoethanolamine, aqueous methyldiethaolamine and aqueous solution of amino acid salts. The performances of these solvents were compared in term of CO_2 removal efficiency. The results showed that the removal efficiency of aqueous solution of amino acid salts was better than the other solvents. The CO_2 removal efficiency was above 90% and the resistance of contactors was below 150Pa with aqueous solution of amino acid salts as absorbents. It is very suitable to the removal of carbon dioxide of flue gas and has a good application prospect.
