2-amino-2-methyl-1-propanol as Additive to Enhance Carbon Dioxide Removal by Monoethanolamine Emulsion Liquid Membrane
S.N. Suahadah and K.S.N. Kamarudin

Abstract:
Aqueous Monoethanolamine (MEA) is widely used as the Carbon dioxide (CO2) absorbent in process industries. Recent technology has shown that a mixture of MEA with other amines can enhance its capability as CO2 absorbent. The addition of 2-amino-2-methyl-1-propanol (AMP) into aqueous phase containing MEA was reported in this study. The aqueous solution was homogenized with the organic solution containing kerosene and Span-80 to produce Emulsion Liquid Membrane (ELM). Rotating disc contactor was used in the CO2 absorption process to maintain the stability of the emulsion. 55.17% of CO2 was removed when 8 mL of MEA was used in the aqueous phase whereas when 8 mL AMP was used, only 41.72% of CO2 was removed. On the other hand, CO2 percentage removal increased to 60.72% when 2 mL of AMP was added into the ELM that containing 6 mL of MEA. Stability of the MEA/AMP mixture ELM after 24 h was 89%. The results indicate that a mixture of MEA/AMP is stable and can enhance the CO2 removal.
